Aspects of Langerhans cells and TNF-α in the cutaneous immunity of anogenital warts

Abstract Background: Anogenital warts are the leading sexually transmitted infection in patients seeking care at specialized clinics. They may display a vast array of forms, according to the interaction of the virus with the host's immunity. Cellular immunity is the epithelium's main form of defense against the virus, involving an active participation of the Langerhans cells and pro-inflammatory cytokines such as TNF-α. Objective: To assess the epithelial immune response of anogenital warts in males, according to the number of lesions presented. Methods: This is a prospective, cross-sectional study carried out at the dermatology outpatient clinic in a tertiary hospital. We included male patients over 18 years of age without comorbidities who had anogenital condylomata and no previous treatments.In order to evaluate the local epithelial immunity, the lesions were quantified, then removed and employed in CD1a immunohistochemistry assays for assessing the morphometry and morphology of Langerhans cells; TNF-α; reaction was used for determining cytokine positivity in the epithelium. Results: 48 patients were included in the study. There was no statistically significant difference as to the number of Langerhans cells, in their morphology, or the presence of TNF-α. However, patients presenting with more Langerhans cells in the lesions had cells with a star-like and dendritic morphology, whereas in those with a lower cell count had cells with a rounded morphology and no dendrites (p < 0.001). Study limitations: Small number of patients analyzed. Conclusion: There was no difference in epithelial immunity between patients having few or many anogenital condyloma lesions as measured by the morphology and morphometry of Langerhans cells and TNF-α; positivity. Such an assessment employing immunity markers differing from the usual ones is expected to yield useful results.

Syphilis among HIV serodiscordant partners associated with Human Papillomavirus Infection in a bisexual man / Sífilis entre parceiros sorodiscordantes para HIV associada à infecção por papilomavírus humano em um homem bissexual

Introduction: Syphilis and HIV infections are sexually transmitted infections whose diagnosis and treatment contribute toward preventing congenital transmission. Objective: To report a case of three sexually transmitted infections detected in a male partner during Couple Consultation and syphilis in the female partner during prenatal care. Case report: A 34-year-old black female G2P1 pregnant woman was referred to an outpatient clinic of sexually transmitted infections in Vitória, Brazil, reporting a 30-day evolution of painless papular lesions in the external genitalia, suggestive of condylomata lata. Nontreponemal tests were positive for syphilis and negative for HIV. The husband reported unprotected receptive anal intercourse and possessed anal condylomatous lesions and perianal condylomata lata. He was positive for both HIV and syphilis. Histopathological findings showed low-grade HPV lesions and the PCR test found 16, 39, and 53 HPV subtypes. Treatment with benzathine penicillin G was successful for both partners. Conclusion: This study emphasizes the need for Couple Consultation during pregnancy to identify and treat possible sexually transmitted infections.

Introdução: As infecções por sífilis e HIV são infecções sexualmente transmissíveis cujo diagnóstico e tratamento contribuem para a prevenção da transmissão congênita.

Application of dermoscopy image analysis technique in diagnosing urethral condylomata acuminata

Abstract: Background: In this study, cases with suspected urethral condylomata acuminata were examined by dermoscopy, in order to explore an effective method for clinical. Objective: To study the application of dermoscopy image analysis technique in clinical diagnosis of urethral condylomata acuminata. Methods: A total of 220 suspected urethral condylomata acuminata were clinically diagnosed first with the naked eyes, and then by using dermoscopy image analysis technique. Afterwards, a comparative analysis was made for the two diagnostic methods. Results: Among the 220 suspected urethral condylomata acuminata, there was a higher positive rate by dermoscopy examination than visual observation. Study limitations: Dermoscopy examination technique is still restricted by its inapplicability in deep urethral orifice and skin wrinkles, and concordance between different clinicians may also vary. Conclusion: Dermoscopy image analysis technique features a high sensitivity, quick and accurate diagnosis and is non-invasive, and we recommend its use.

Mucinosis. Presentación de caso / Mucinosis. Presentation of case

Mucinosis (REM síndrome), es una rara enfermedad cutánea, descrita hace más de 30 años por Steigleder, afectando predominantemente a mujeres de edad avanzada. Clínicamente presenta áreas con eritema persistente, pápulas que pueden confluir, formando placas con escamas. La etiología aún no está bien esclarecida, pero diversos factores como la luz ultravioleta, trastornos inmunológicos, infecciones virales, han sido relacionados o asociados con la inducción de la misma. Se presenta un reporte de caso de un paciente masculino de 20 años, con antecedentes de haber padecido de Condilomas Acuminados, además presentó otras lesiones cutáneas caracterizadas por placas alopécicas, con discreta infiltración en número de 10 en cuero cabelludo y lesiones en placas, infiltradas, de 3 a 5 centímetros de diámetro en número de 2, de bordes precisos en tercio inferior central de la espalda. Se realizó biopsia de piel, donde se corrobora el diagnóstico de Mucinosis, posteriormente el paciente ingresó en el servicio de Nefrología en el hospital de Cárdenas con diagnóstico de Insuficiencia Renal Crónica (AU).

Mucinosis (REMsyndrome), he is a rare cutaneous, described disease he does over 30 years for Steigleder, affecting predominantly women late in years. Clinically he presents areas with persistent erythema, pápulas that they can converge, forming plates with scales. The etiology not yet is very illustrious, but various factors like the ultraviolet light, immunogenic upsets, viral infections, they have been related or associated with the induction of the same. He encounters a report of case of a masculine patient of 20 years, with background to have suffered from Condylomas Acuminados, besides he presented another cutaneous injuries characterized by plates alopécicas, with discreet infiltration in number of 10 in scalp and injuries in plates, spies, of 3 a 5 cms of diameter in number of 2, of precise borders in inferior central third part of the back. The patient accomplished biopsy of skin himself, where Mucinosis's diagnosis is corroborated, at a later time he entered in Nefrología's service at Cárdenas's hospital with diagnosis of renal chronic Insuficiencia (AU).

Verrugosis generalizada con linfedema, inmunodeficiencia y displasia genital: síndrome WILD / Generalized verrucosis with limphoedema, immunodeficiency and genital dysplasia: WILD syndrome

La verrugosis generalizada es un rasgo común a diferentes síndromes de inmunodeficiencia, cuyo prototipo es la epidermodisplasia verruciforme (EV). Se presenta una paciente con síndrome WILD (Warts, Immunodeficiency, Lymphoedema, anogenital Dysplasia), que consultó por verrugas profusas, con displasia genital y linfedema. La presencia de DNA para los papilomavirus de los grupos I y II se reveló con hibridización molecular por captura híbrida en microplaca para detección del DNA de HPV de lesiones de cuello uterino. La inmunofenotipificación en sangre periférica demostró población linfoide con moderado aumento de poblaciones NK y TNK, sin evidencia inmunofenotípica de población B clonal. Las verrugas planas mejoraron con retinoides sistémicos e imiquimod tópico. La displasia genital desapareció luego de la vacunación para HPV con vacuna cuadrivalente (AU)

Generalized verrucosis is a common characteristic of several immunodeficiency disorders whose prototype is the epidermodysplasia verruciformis. We report a patient with WILD SYNDROME (Warts, Immunodeficiency, Lymphoedema and anogenital Dysplasia) who consulted for profuse warts, genital dysplasia and limphoedema. The presence of DNA from papillomavirus groups I and II was revealed by molecular hybridization with hybrid capture in microplate for HPV DNA detection of uterine cervical lesions. Immunophenotyping in peripheral blood showed lymphoid population with moderate increase in NK and TNK populations without immunophenotypic evidence of clonal B population. Flat warts improved with systemic retinoids and topical imiquimod. The genital dysplasia disappeared after vaccination with quadrivalent HPV vaccine (AU)

Cáncer anal: lesiones precursoras y cáncer temprano. consideraciones sobre terminología, diagnostico y terapéutica / Anal cancer: precursor lesions and early cancer. considerations on terminology,diagnosis and treatment

Las lesiones precursoras y formas tempranas del cáncer de ano y de la zona perianal ha sido en los últimos años mejor reconocidas y definidas; ello ha ido en paralelo a un interés cada vez mayor en esta patología debido a su incidencia creciente. En esta revisión se analiza el tema, actualizando los aspectos patogénicos que vinculan las neoplasias anales con subtipos oncogénicos del Papilomavirus Humano, y correlacionándolo con la existencia de poblaciones en riesgo y de alteraciones inmunitarias predisponentes o asociadas. Se describe la expresión morfológica de las lesiones precursoras y tempranas, en el contexto mas amplio de las neoplasias intraepiteliales similares de la zona genital baja. Tambien se realiza una puesta al día de las diversas técnicas de diagnóstico disponibles en este momento desde el punto de vista proctológico y antomopatologico y finalmente, una actualización de las diversas opciones terapéuticas y los cambios de enfoque y conducta que se plantean en lesiones anales y perianales diagnosticadas en etapas relativamente tempranas de su evolución.

The precursor precancerous lesions and early invasive cancer of the anus and the perianal area have been better recognized and defined in the last decade; it has been also a greater interest in this kind of precancers and cancers because of their increasing incidence. We analyzed in this paper this subject, updating the knowledge about the pathogenic link between anal neoplasias and oncogenics subtypes of Human Paplilomavirus, and correlating this neoplasias with the populations at risk and associated/predisposing immune alterations. The morphologic expression of the precursor and early invasive lesions is described, in the full context of similar intraepithelial neoplasias of the low genital area. Also we made an update of the proctologic and cytopathologic diagnostic techniques available at this moment and, finally, the therapeutic options and the changes of approach in anal and perianal preneoplastic and neoplastic lesions diagnosed in early stages of their evolution were revised.

Genital warts: comparing clinical findings to dermatoscopic aspects, in vivo reflectance confocal features and histopathologic exam

Genital warts can be diagnosed through physical examination and confirmed by histopathology. Noninvasive methods are useful for ruling out other diagnoses with no harm to the patient. In this study the clinical findings were compared to dermoscopy, reflectance confocal microscopy (RCM), and to histopathology findings, in order to determine possible patterns that can aid diagnosis of the lesion. It was possible to identify structural changes on reflectance confocal microscopy that are already known by dermoscopy, in addition to cellular changes previously seen only by histopathological examination. This study shows the use of reflectance confocal microscopy in cases of genital warts, providing important information that can be used in further studies.

Condiloma acuminado gigante (tumor de Buschke-Lowenstein): presentación de un caso / Giant acuminated condiloma (Bushke-Lowenstein tumor): case report

El condiloma gigante del pene o tumor de Buschke-Lowenstein, es un tumor epitelial benigno de origen viral y sexualmente transmisible, que en raros casos puede malignizar. Su histología se caracteriza por papilomatosis y acantosis endo y exofítica. Existen diferentes tratamientos del tumor, pero el más efectivo es la resección quirúrgica radical para evitar recidivas y malignización. Describir y documentar un caso de un condiloma acuminado gigante o tumor de Buschke-Lowenstein. Revisaremos la bibliografía existente sobre este tipo de tumor. Paciente masculino de 51 años de edad con lesiones vegetantes de 6 años de evolución, que se extienden desde la región perianal a perineal y ambas regiones inguinales, escroto y base de pene, a quien se le realizó resección quirúrgica amplia de la lesión. El estudio anatomopatológico reporta condiloma acuminado gigante, con inflamación crónica severa sobre agregada, el paciente mantiene resultados funcionales y estéticos muy satisfactorios después de la cirugía. El tumor de Buschke-Lowenstein es un condiloma acuminado gigante que se presenta con más frecuencia en hombres, benigno, cuyas lesiones clínicas son mayores de 10 cm, por lo que el tratamiento de elección debe ser siempre quirúrgico.

The giant condyloma of the penis or denominated Buschke-Lowenstein tumor is a benign epithelial tumor of viral origin and its sexually transmissible, in rare cases can become transformation to malignant. Histology is characterized by papillomatosis and acanthosis endophytic and exophytic. There are different treatments of the tumor, but the most effective of them is the radical surgical resection to prevent recurrences and the malignant transformation of the lesion. To describe and document a case view of us in our institution of giant condyloma acuminatum or Buschke-Lowenstein tumor. We will review the existent literature on this type of tumor. Male patient 51 years old with vegetative lesions of 6 years of evolution, extending from the perineal and per anal region to groins, the scrotum and the penis base, who underwent extensive surgical resection treatment. The pathology reports giant condyloma acuminatum with severe chronic inflammation, actually the patient maintains satisfactory functional and aesthetic results after the surgery. The Buschke-Lowenstein tumor is a giant condyloma acuminated it´s occurs more often in men, benign clinical lesions which are greater than 10 cm, so the treatment of choice should always be the surgical.

Modelo de regresión logística binaria para el diagnóstico morfológico de lesiones por virus del papiloma humano (VPH) en la boca / Usefulness of Toki's morphological criteria for the diagnosis of oral lesions caused by human papillomavirus

Background: Oral lesions caused by human papillomavirus (HPV), share morphological features which may complicate their diagnosis. Aim: To analyze the usefulness of Toki's morphological criteria for the diagnosis of HPV lesions in cervix, in the diagnosis of oral lesions. Materials and Methods: Retrospective study of 355 oral lesions by HPV. The pathologic evaluation was carried out three times by the same examiner with a Kappa coefficient of 0.780 (p = 0.01). Toki's criteria scored the presence of acanthosis as 1, dyskeratosis as 1, koilocytosis as 4, basilar hyperplasia as 1, bi or multinucleated cells as 2 and papillomatosis as 1. The information was analyzed using χ² and binary logistic regression. Results: Fifty eight percent of cases (207) corresponded to Verruca Vulgaris (VV), 23% (80) to Multifocal Epithelial Hyperplasia (MEH), and 19% (68) to Condyloma Acuminatum (CA). According to Toki's criteria, 76/80 MEH lesions, 195/207 of VV and 67/68 of CA, had a score equal or greater than six. A logistic regression showed that dyskeratosis suggests the presence of MEH. The presence of acanthosis and dyskeratosis in HPV oral lesions are not useful criteria for the diagnosis of VV. No significant associations with CA were found. Conclusions: The morphological criteria studied do not predict their possible viral etiology and do not allow a differential diagnosis of the lesions. Therefore, polymerase chain reaction studies are required to identify high-risk HPVs or sexually transmitted viral lesions.

Condiloma acuminado gigante del pene / Giant condyloma acuminata of penis

Introducción: el condiloma acuminado del pene en una entidad nosológica frecuente con alto índice de recidivas. Es producido por el virus del papiloma humano que se asocia, íntimamente, a la aparición del cáncer cérvico-uterino. Objetivos: presentar un caso de condiloma acuminado del pene, de gran tamaño, y aspectos de su diagnóstico y tratamiento. Métodos: paciente de 19 años de edad que asiste a la consulta de Urología del Hospital Militar Central Dr. Carlos J. Finlay, en el mes de mayo del 2010, por presentar una tumoración en el pene de 3 meses de evolución. Refirió la práctica habitual del coito desprotegido y, al examen físico, tenía un tumor de aproximadamente 3 cm de diámetro, aspecto de coliflor y secreción amarillenta espesa, que abarcaba parte del surco balano-prepucial y del frenillo. Para realizar esta investigación se contó con el consentimiento informado del paciente. Resultados: por presentar resistencia al tratamiento habitual para condiloma acuminado y su gran tamaño, se realizó biopsia la que confirmó la presencia de esta entidad nosológica. Se hizo la exéresis total más la circuncisión en el quirófano. El informe anátomo-patológico final ratificó el diagnóstico. El paciente, tras un año de operado, está asintomático y ha incorporado prácticas sexuales seguras. Conclusiones: ante la presencia de condilomas acuminados del pene de gran tamaño, con rápido crecimiento y rebeldes al tratamiento tópico habitual se debe realizar biopsia de la lesión y una vez obtenida su confirmación histológica, proceder a su exéresis total en el quirófano

Introduction: the penis condyloma acuminata is a frequent disease entity with a high rate of relapses. It is caused by the human papilloma virus closely associated with the appearance of cervical-uterine cancer. Objectives: to present a case of a giant penis condyloma acuminata and the features of its diagnosis and treatment. Methods: patient aged 19 came to Urology consultation of the Carlos J. Finlay Central Military Hospital in May, 2010 due to a three months course penis tumor. He referred the unprotected sexual practice and at physical examination we noted a tumor of approximately 3 cm diameter of a cauliflower appearance and a thick yellowish secretion involving the balanopreputial groove and the frenum. For present research authors got the informed consent given by patient. Results: due to resistance to habitual treatment for condyloma acuminata ant its large size, a biopsy was carried out confirming the presence of this disease entity. In the operating theater a total exeresis was performed plus circumcision. The final anatomic-pathologic report confirmed the diagnosis. The patient after a year to be operated on remains asymptomatic and now has safe sexual practices. Conclusions: in face of the presence of giant penis condyloma acuminata with a fast growth and refractory to habitual topical treatment it is necessary to make a biopsy of lesion and after to achieve its histological confirmation, to perform total exeresis in the operating room

Morphometric analysis of dendritic cells from anal mucosa of HIV-positive patients and the relation to intraepithelial lesions and cancer seen at a tertiary health institution in Brazil / Análise morfométrica das células dendríticas da mucosa anal de pacientes HIV-positivos e relação com as lesões intraepiteliais e o câncer numa instituição de saúde terciária no Brasil

PURPOSE: To morphometrically quantify CD1a+ dentritic cells and DC-SIGN+ dendritic cells in HIV-positive patients with anal squamous intraepithelial neoplasia and to evaluate the effects of HIV infection, antiretroviral therapy and HPV infection on epithelial and subepithelial dendritic cells. METHODS: A prospective study was performed to morphometrically analyze the relative volume of the dendritic cells and the relationship between anal intraepithelial neoplasia and cancer in HIV-positive patients from the Tropical Medicine Foundation of Amazonas, Brazil. All patients were submitted to biopsies of anorectal mucosa to perform a classic histopathological and immunohistochemical analysis, employing antibodies against CD1a and DC-SIGN for the morphometric quantification of dendritic cells. RESULTS: HIV-negative patients displayed a CD1a DC density significantly higher than that of HIV-positives patients (3.75 versus 2.54) (p=0.018), and in patients with severe anal intraepithelial neoplasia had correlated between DC CD1a density with levels of CD4 + cells (p: 0.04) as well as the viral load of HIV-1 (p: 0.035). A not significant rise in the median density of CD1a+ DC was observed in the HIV positive/ HAART positive subgroup compared to the HIV positive/ HAART negative subgroup. The CD1a+ DC were also significantly increased in HIV-negative patients with anorectal condyloma (2.33 to 3.53; p=0.05), with an opposite effect in HIV-positive patients. CONCLUSIONS: Our data support an enhancement of the synergistic action caused by HIV-HPV co-infection on the anal epithelium, weakening the DC for its major role in immune surveillance. Notoriously in patients with severe anal intraepithelial neoplasia, the density of CD1a+ epithelial dendritic cells was influenced by the viral load of HIV-1. Our study describes for the first time the density of subepithelial DC-SIGN+ dendritic cells in patients with anal severe anal intraepithelial neoplasia and points to the possibility that a specific therapy for HIV induces the recovery of the density of epithelial DC.

OBJETIVO: Quantificar morfometricamente as células dendríticas DC CD1a+ e DC DC-SIGN+ em pacientes HIV positivos portadores de neoplasia escamosa intraepitelial anal e avaliar os efeitos da infecção pelo HIV, da terapia antirretroviral e da infecção pelo HPV sobre as células dendríticas epiteliais e subepiteliais. MÉTODOS: Um estudo prospectivo foi realizado para analisar morfometricamente o volume relativo das células dendríticas e as relações entre neoplasia intraepitelial anal e o câncer em pacientes HIV positivos da Fundação de Medicina Tropical do Amazonas, Brasil.Todos os pacientes foram submetidos a biópsia da mucosa retal para realizar uma análise clássica histopatológica e imunohistoquímica utilizando anticorpos contra anti-CD1a e anti-DC-SIGN, para a quantificação morfométrica das células dendríticas. RESULTADOS: Os pacientes HIV negativos apresentaram densidade das DC CD1a+ significativamente maior do que a dos pacientes HIV positivos (3,75 versus 2,54) (p:0,018), e os pacientes com severa apresentaram correlação das DC CD1a com os níveis de células TCD4(p:0,04) assim como a carga viral do HIV-1 (p:0,035). Observamos no subgrupo HIV-positivo/HAART positivo elevação não significativa na mediana da densidade das DC CD1a+ em relação ao grupo HIV-positivo/HAART negativo. As DC CD1a+ também se elevaram nos pacientes HIV negativo portadores de condiloma anorretal(2,33 para 3,53; p:0,05), com efeito inverso nos pacientes HIV positivos. CONCLUSÕES: Nossos dados confirmam a potencialização da ação sinérgica representada pela coinfecção HIV-HPV sobre o epitélio anal, fragilizando as DC em sua função primordial de vigilância imune. Notoriamente nos pacientes com neoplasia intraepithelial anal grave, a densidade das DC CD1a+ epiteliais sofreu influência da carga viral do HIV-1. Nosso estudo descreveu pela primeira vez a densidade das DC subepiteliais DC-SIGN+ em pacientes com neoplasia intraepithelial anal severa e apontamos para a possibilidade de que a terapia específica para o HIV induza a recuperação da densidade das DC epiteliais.

Melanosis of the vagina and human papillomavirus infection, an uncommon pathology: Case Report / Melanosis de la vagina e infección por virus del papiloma humano, una patología poco común: Reporte de un Caso

Benign melanotic lesions of the vagina are uncommon and only a few cases have been reported in the literature. A 34-year-old woman was referred because of a Vaginal Intraepithelial Neoplasia 1 biopsy result. On the gynecological examination, two different hyperpigmented areas were noted in the vagina. The colposcopic visualization of the cervix and vagina found an aceto-white lesion at the right lateral wall of the upper third of the vagina. Biopsies from three areas were taken. Histological study reported a melanosis of the vagina and HPV infection. An immunohistochemical panel of epithelial markers was performed in vaginal samples, such as Cytokeratin AE1/AE3 and epithelial membrane antigen, mesenchymal marker: vimentin; melanocytic makers: protein S-100 and HMB45 (Human Melanoma Black); proliferating cell marker: proliferating cell nuclear antigen (PCNA), and P-53 oncoprotein. High Risk (16, 18, 31, 45) and Low Risk (6, 11) HPV types were studied by In Situ Hybridization using the same vaginal samples. CK, EMA and Vimentin were 2+. Melanocytic markers, HMB45 and S100, and PCNA were 1+ in basal cell layer. P-53 was negative. The melanotic tissue and acetowhite lesion were positives to HPV Types 6,11. In conclusion, melanosis of the vagina is a uncommon benign pathology. Usually, melanosis is present in women over 40 years old. We present a case of melanosis of the vagina in a young woman infected with low-risk HPV types and review the literature.

Las lesiones melanóticas de la vagina son infrecuentes. y Solo pocos casos han sido reportados. Se presenta el caso de una mujer de 34 años quien es referida con diagnóstico de una Neoplasia Intraepitelial Vaginal 1. Al examen ginecológico, se encontraron dos áreas hiperpigmentadas en la vagina. La exploración colposcópica del cuello uterino y vagina reveló la presencia de una lesión aceto-blanca en la pared lateral derecha del tercio superior de la vagina. Muestras de biopsias fueron tomadas en dichas áreas. El estudio histológico reportó una melanosis de la vagina y una infección por el virus del Papiloma Humano (VPH). Se realizó un panel de estudio inmunohistoquímico de marcadores epiteliales en las muestras vaginales: tales como citoqueratina AE1/AE3 y antígeno epitelial de membrana; marcador mesenquimal: vimentin; marcadores melanóticos: proteina S-100 y HMB45 (Human Melanoma Black); marcadores de proliferación celular: antígeno de proliferación nuclear (PCNA), y la oncoproteína P-53. Se realizó Hibridización In Situ para establecer los tipos de alto (16, 18, 31, 45) y bajo (6, 11) riesgo de VPH en las muestras vaginales. Los marcadores CK, EMA y Vimentin fueron 2+. Los marcadores melanótico, el HMB45 y el S100, y el PCNA fueron 1+ en la capa basal. P-53 fue negativo. El tejido melanótico y la lesión acetoblanca fueron positivos al VPH 6,11. En conclusión, la melanosis vaginal es una patología poco frecuente. Usualmente, se ha reportado en mujeres mayores de 40 años. Presentamos un caso de una melanosis de la vagina infectada con un tipo de VPH de bajo riesgo en una mujer joven y una revisión de la literatura.

Objectives: This article reports a case of oral papilloma in the ventral tongue associated to previous penile Condyloma acuminatum. Materiais and methods: A white male, 28 years old, was referred to the Propaedeutic Stomatology University Clinic claiming of a nodule at the base of the tongue. He had a penile lesion removed seven months before, with diagnosis of Condyloma acuminatum. Clinical exarnination showed a 0.5 cm intraoral pedunculated nodular papillomatous asymptomatic lesion, located in the tongue frenulum. Excisional biopsy was performed. Results: Histological examination showed a benign epithelial proliferative lesion, presenting numerous long papillary projections with thinned extremities, lined by stratified epithelium, with areas of increased thickness and severa I coilocytotic cells characterized by cytoplasmic vacuolization and perinuclear halos, receiving the diagnosis of squamous papilloma. Conclusion: The oral squamous papilloma, in this case, suggests inter-relationship with the penile Condyloma acuminatum. Dental professionals must be able to make a good clinical examination and anamnesis in order to promote the patients diagnosis, treatment and orientation about the risks and prophylactic measures regarding this lesion.

Remoção de condiloma acuminado em porção lateral de língua:relato de caso / Condyloma acuminatum remotion of the lateral tongue: case report

Objetivo: relatar o caso de um paciente portador de lesão sugestiva de condiloma acuminado na porção lateral de língua, em decorrência da prática frequente de sexo oral com diversas parceiras. Método: estudo descritivo de fonte secundária de paciente atendido na clínica odontológica do HGeBe. Resultado: Presença de tumor na porção lateral da língua, séssil, apresentando cerca de 2mm de diâmetro. o laudo histopatológico confirmou o diagnóstico inicial de condiloma acuminado. Conclusão: o tratamento cirúrgico é capaz de erradicar a lesão, mas o vírus pode persistir no epitélio seja na região genital, anal ou cavidade oral. Em razão do alto poder de infectabilidade do HPV, possível malignização e também devido o aspecto social envolvido com a doença, são necessários relatos mais concisos sobre a infecção por este vírus na mucosa oral, seu estado latente e subclínico.

Aim: a case report of a patient with a suggestive lesion of condyloma acuminatum in the tongue?s lateral portion, caused by oral and anal sex practice, frequently with diversified partners. Method: The patient was attended at HGeBe Odontologic Clinic, where he was submitted to the basic anamneses, and related that he constantly practiced oral and anal sex, without a fixed partner. In clinical examinations, it was observed a tumor in the tongue?s lateral portion, sessile, presenting about 2mm of diameter. After pre-surgical laboratories exams, the patient was submitted to surgical procedure for removing the lesion and then, the sample was taken to a histopathologic examination. Results: histopathological findings confirmed the initial diagnosis of condyloma acuminatum. Conclusions: the surgical treatment is capable to eradicate the lesion, but the virus can persist in the epithelium, anal region and, also, in the oral cavity. Regarding HPV high power infectibility, possible malignization and the social aspects involved, more concise case reports about the infection of this virus in oral mucosa are necessary, observing it?s latent and subclinical state.

Quanto a escova deve ser introduzida no canal anal para avaliação citológica mais eficaz? / How deep must the brush be introduced in the anal canal for a more effective cytological evaluation?

OBJETIVO: A sensibilidade da citologia anal varia amplamente na literatura, entre 45 por cento e 98 por cento, o que pode ocorrer devido à falta de padronização quanto à distância que a escova deve ser introduzida no canal anal. Desta forma, nosso objetivo foi investigar se o local de coleta influencia no resultado desse exame. MÉTODOS: Colhemos amostras com escova introduzida 4 cm no canal anal de 114 doentes (Grupo A) e 2 cm em outros 94 pacientes (Grupo B), antes do exame proctológico. Realizamos cinco rotações com a escova antes de retirá-la e a esfregar sobre lâmina de vidro, posteriormente submetida ao exame citopatológico padrão. Todos os doentes são HIV-positivo. Submetemos os resultados à avaliação estatística. RESULTADOS: No Grupo A, 39 doentes possuíam condilomas no canal anal e a citologia foi positiva em 29 deles (74,3 por cento). Também observamos alterações citológicas em 30 de 75 doentes (40 por cento) sem lesões clínicas no canal anal. No Grupo B, havia 54 doentes com condilomas no canal anal e em 13 (24,1 por cento) houve confirmação citológica. Em 40 outros, sem lesões clínicas pelo HPV, notamos que em nove (22,5 por cento) havia anormalidades citológicas. Os testes estatísticos revelaram que os exames realizados nos doentes do Grupo A foram mais eficientes. CONCLUSÃO: Os espécimes coletados com escovas inseridas mais profundamente no canal anal melhoraram a eficácia do exame.

OBJECTIVE: In literature, sensitivity of Pap smears ranges widely from 45 to 98 percent. Possibly this is because there is no standard for how far the brush should be introduced into the anal canal. The aim was to evaluate whether the sampling site has an influence on the results of anal Pap smears. Design and setting. This is a non-randomized, non-blinded, retrospective review carried out in the Proctology and Pathology Sectors, Emilio Ribas Infectious Diseases Institute. METHOD: We obtained specimens with brushes introduced 4 cm into the anal canal in 114 patients (Group A) and 2 cm in 94 patients (Group B), before anorectal examination. These brushes were rotated five or six times before being withdrawn and rubbed on a slide that underwent Pap testing using standard cytopathology laboratory equipment. All patients were HIV-infected. Statistical tests were used. RESULTS: In Group A, 39 patients had anal canal condylomas and the cytology was positive in 29 of them (74.3 percent). We also observed cytological alterations in 30 of 75 patients (40 percent) without clinical lesions in the anal canal. In Group B, there were 54 patients with condylomas and 13 of them (24.1 percent) were confirmed by cytology. In 40 patients with no clinical lesions, we observed that nine (22.5 percent) had cytological abnormalities Statistical analysis revealed that examination in Group A was more efficient. CONCLUSION. Specimens collected by inserting the brush deeper into the anal canal improved the efficiency of anal Pap smears.

Relato de dois casos de condiloma imaturo: descrição dos achados colposcópicos, cervicográficos, cito-histológicos e moleculares / Report of two cases of immature cervical condyloma: description of colposcopic, cervicographic, cytohistological and molecular findings

Por meio da descrição de dois casos, os autores visam chamar a atenção para a forma de apresentação do condiloma imaturo ou metaplasia papilar imatura atípica (MPIA), assim como para as dificuldades de detecção citológica, classificação histológica e interpretação adequada. As características do condiloma imaturo ao colposcópio e na cervicografia foram relacionadas com seu aspecto histopatológico e com o padrão colposcópico do condiloma acuminado típico cervical. Exames citopatológicos resultaram negativos ou com células escamosas atípicas de significado indeterminado (ASCUS). Em um dos casos foi realizada captura híbrida para papilomavírus humano (HPV), que identificou tipos virais de alto e baixo graus. A partir do estudo dos casos concluiu-se que: a) o condiloma imaturo pode ser identificado por exame colposcópico ou cervicográfico, podendo ser precedido ou acompanhado do diagnóstico citológico de ASCUS ou detecção de HPV por teste molecular; b) a caracterização histopatológica dessas lesões como de baixo grau evita o tratamento cirúrgico desnecessário.

Based on the report of two cases, we aim to highlight the presentation of immature condyloma or atypical papillary immature metaplasia (AIM) as well as the difficulties in its cytological detection, histopathological classification and accurate interpretation of results. The colposcopic and cervicographic characteristics of the immature condyloma were related to its histopathological features and the colposcopic standard of acuminated condyloma. Cytopathological exam results were negative or presented atypical squamous cells of undetermined significance (ASCUS). In one case, a hybrid capture test for human papillomavirus (HPV) was carried out, what identified viral types of high and low grades. The study concluded that: 1) immature condylomas may be identified by means of colposcopic or cervicographic exam, and may be preceded or followed by a cytological diagnosis for ASCUS or HPV detection using molecular test; 2. histopathological characterization of these lesions as low grade avoids unnecessary surgical treatment.
