RESUMO
OBJECTIVE: Around 70% of vaginal cancers and 40-50% of vulvar cancers are attributable to human papillomavirus (HPV). Globally the burden of these diseases is estimated to grow due to the increasing HPV prevalence and rapidly aging global population. We aimed to examine if HPV screening for cervical cancer has an additional beneficial effect in preventing vaginal and vulvar cancers. To assess this, we used long-term follow-up data from the Finnish randomized HPV screening trial. METHODS: Between 2003 and 2008, over 236,000 women were individually randomized (1:1) to primary HPV or cytology screening in Southern Finland. We followed this cohort up to the year 2020. To compare the study arms, we calculated site-specific and pooled incidence rate ratios (IRRs) and mortality rate ratios (MRRs) for vaginal and vulvar cancers using Poisson regression. RESULTS: During 3,5 million person-years of follow-up, the IRR for vaginal cancer in the HPV arm compared to the cytology arm was 0.40 (95% CI 0.17-0.88) and the corresponding MRR was 0.74 (95% 0.21-2.24). The corresponding IRR for vulvar cancer was 0.73 (95% 0.50-1.08) and the MRR was 0.64 (95% 0.23-1.62). The pooled IRR was 0.67 (95% 0.47 ̶ 0.95) and MRR 0.67 (95% 0.31 ̶ 1.37). CONCLUSION: We found lower incidence of vaginal cancers with HPV screening compared to cytology screening. To validate our results, we recommend analyzing data on vaginal and vulvar cancers also from other HPV screening studies.

Benign and malignant neoplasms of the vagina are rare. We report 3 primary vaginal polypoid lesions involving the upper or mid-vagina in patients aged 40, 60, and 67 years. The lesions bore a striking morphologic resemblance to benign endocervical or endometrial polyps and we suggest the designation Mullerian polyp of the vagina. As far as we are aware, similar cases have not been reported previously in the literature. Follow-up ranging from 6 to 21 months has been uneventful. In reporting these cases, we discuss the possible origin and differential diagnosis and review vaginal lesions with a benign glandular component.

PURPOSE: This study aimed to explore the clinical characteristics and risk factors associated with cervical intraepithelial neoplasia (CIN) when coexisting with vaginal intraepithelial neoplasia (VAIN). METHODS: We analyzed the clinical data of 212 patients diagnosed with CIN, including 50 patients with concurrent VAIN. The groups were compared to identify distinct clinical features and independent risk factors for the co-occurrence of CIN and VAIN, using logistic regression analysis. RESULTS: Patients with both CIN and VAIN had a median age of 57, significantly older than the 41-year median age of patients with CIN only (P < 0.05). A higher prevalence of HPV infection (98.0%) was observed in the CIN and VAIN group, with a notable rate of multiple HPV infections (67.3%) compared to the CIN-only group (P < 0.05). Educational levels were significantly lower in the combined CIN and VAIN group (P < 0.05). HPV16, 33, and 52 were identified as significant types for single and multiple infections. Multivariate analysis confirmed age as an independent risk factor for CIN with VAIN (P < 0.05). VAIN3 patients were more likely to exhibit HSIL and ASC-H, whereas VAIN1 cases tended to correspond with ASCUS and LSIL diagnoses. CONCLUSION: The co-occurrence of CIN and VAIN is significantly influenced by patient age and educational level. The findings advocate for more diligent vaginal examination during colposcopy in older patients, particularly those with multiple HPV infections and cytological abnormalities, to enhance the early detection of vaginal lesions and prevent missed diagnoses and treatments. Additionally, the high prevalence of HPV infection, especially with certain types, underscores the importance of HPV monitoring in this patient population.

Vaginal intraepithelial neoplasia (VaIN), a precancerous lesion associated with human papillomavirus (HPV), impacts women's health and quality of life. However, the natural progression of VaIN after hysterectomy remains uncertain, due to its low incidence. The existing literature predominantly consists of single-center retrospective studies lacking robust evidence-based medicine. The management of VaIN after hysterectomy is diverse and controversial, lacking a consensus on the optimal approach. Therefore, it is imperative to investigate the development of VaIN after hysterectomy, emphasizing the importance of accurate diagnosis and effective management strategies.

OBJECTIVE: This study aimed to investigate the characteristics and screening history of vaginal intraepithelial neoplasia (VaIN) or vaginal cancer and compare the sensitivity of cytology and human papillomavirus (HPV) tests on the cervix against vaginal and cervical high-grade squamous intraepithelial lesion or cancer. METHODS: This study included patients who underwent colposcopy-directed biopsy and were diagnosed with VaIN or vaginal cancer from February 2013 to November 2022. Clinical information was obtained from the medical records of the department. Statistical analysis was performed on SPSS 26.0 (IBM Corp, Armonk, NY) using t test, chi-square, and Fisher exact tests. RESULTS: A total of 1,166 patients were included in this study. The median age of VaIN2+ patients was 50.5 years, whereas VaIN1 reported a median age of 42.1 years old, p < .001. This study reported that VaIN was significantly and positively correlated with cervical lesions (r = 0.244). The high-risk HPV (hr-HPV) detection rate was 88.2% (858/973) in VaIN and 95.2% in VaIN2+. Human papillomavirus 16 was the most prevalent HPV type in VaIN2+, which accounted for 54.9%, followed by HPV58 (19.5%), HPV52 (15.2%), HPV51 (12.2%), and HPV18 (11.0%). The sensitivity of hr-HPV and cytology tests on the cervix for detecting VaIN2+ was 94.7% and 83.4%, respectively. Both tests were not significantly different from detecting cervical intraepithelial neoplasia 2+. CONCLUSIONS: Human papillomavirus 16 is the dominant HPV type in vaginal precancer lesions. Cervical cancer screening has similar sensitivity for VaIN2+ as for cervical intraepithelial neoplasia 2+, with hr-HPV testing showing higher sensitivity than cytology.

Background and Objectives: Neoplasms of the vagina are rare and account for 1-2% of all tumors of the female reproductive system. Primary neoplasms of the vagina are most often carcinomas originating from squamous or glandular epithelium. Of the primary glandular tumors, clear cell, endometrioid, and serous adenocarcinomas are the most common types, while mucinous and mesonephric types are very rare. Mucinous adenocarcinoma is histologically subclassified into endocervical and intestinal types. We add to the existing literature another case of an extremely rare gynecological neoplasm-primary vaginal mucinous adenocarcinoma (PVMAC) intestinal type associated with vaginal villous adenoma with high-grade dysplasia. We discuss the clinical, radiological and morphological features of this rare entity. Materials and Methods: We report a case of a 59-year-old woman with PVMAC intestinal type associated with vaginal villous adenoma with high-grade dysplasia. The patient was evaluated with a gynecological exam, and biopsy, curettage and tumor excision were performed. The positron emission tomography-computed tomography (PET/CT) scan, at the level of the pelvis, supported the primary location of the disease. Histological and immunohistochemical methods were applied. Results: The gynecological examination of the vagina revealed an exophytic polypoid mass with a diameter of 3 cm, located on the posterior wall, in the area of introitus vaginae. The PET/CT scan revealed a hypermetabolic malignant formation involving the vagina and anal canal, without evidence of pelvic and inguinal lymphadenopathy, and also, it excluded disease at sites other than the vagina. The histological and immunohistochemical investigations, as well as the clinical and radiological data, lent support to the diagnosis "primary vaginal mucinous adenocarcinoma intestinal type". Conclusions: PVMAC intestinal type is a rare gynecological pathology, which presents a serious challenge for oncogynecologists, radiologists and pathologists.

Mesothelioma of the testicular vagina is a rare malignant tumour, most often discovered by chance. The rarity of this type of tumour has not led to the development of specific guidelines. Median survival is estimated at 30 months. The lack of data and official recommendations makes surgical and medical management and follow-up difficult. Men who have not undergone radical orchiectomy die very rapidly after diagnosis. The remission rate at 1 year post-orchidectomy is 47 %, the recurrence rate at 1 year is 53 % and 92 % of relapses occur within 5 years post-operatively. The treatment option of hemiscrotectomy in the first instance has rarely been used; a second-look resection with negative margins may be proposed. The usefulness of adjuvant chemotherapy and/or radiotherapy has not been clearly demonstrated. Local recurrence is accompanied by metastasis in 85 % of cases. In the case of metastatic cancer (15 %), the retro-peritoneal, inguinal and iliac lymph nodes may be invaded. Follow-up by injected thoraco-abdomino-pelvic CT scan is recommended every 3 months for 2 years, then once a year for 3 years, for a total of 5 years of close follow-up. The long-term recurrence rate is 3 %.
Le mésothéliome de la vaginale testiculaire est une tumeur maligne rare et souvent de découverte fortuite. Sa rareté d'apparition n'a pas permis de développer des recommandations spécifiques. La survie médiane est estimée à 30 mois. Le manque de recommandations officielles rend sa prise en charge chirurgicale, médicale et son suivi difficiles. Les hommes n'ayant pas bénéficié d'orchidectomie radicale décèdent très rapidement après le diagnostic. Le taux de rémission à 1 an post-orchidectomie est de 47 %, le taux de récurrence à 1 an est de 53 % et 92 % des rechutes se font endéans les 5 ans post-opératoires. L'option thérapeutique par hémi-scrotectomie en première intention a rarement été pratiquée, une résection de «second look¼ en marges saines peut être proposée. L'utilité d'une chimiothérapie et/ou d'une radiothérapie adjuvante n'a pas été clairement démontrée. Une rechute locale est accompagnée de métastases dans 85 % des cas. En cas de cancer d'emblée métastatique (15 %), les relais ganglionnaires rétro-péritonéaux, inguinaux et iliaques peuvent être envahis. Un suivi par scanner thoraco-abdomino-pelvien injecté est recommandé tous les 3 mois pendant 2 ans, puis 1 fois par an pendant 3 ans pour un total de 5 ans. Le taux de récidive au long cours est de 3 %.

Rhabdomyosarcomas are the most common soft-tissue sarcomas, found usually in the younger age group. Histologically, they are subdivided into embryonal, alveolar, pleomorphic and not otherwise specified. They have a heterogenous appearance on imaging with few additional characteristic features based on the subtype. Botryoid variant of embryonal rhabdomyosarcoma commonly involves the genitourinary and the biliary system. They can be multifocal. Most of these lesions have a heterogenous appearance on imaging with areas of necrosis and haemorrhage. On ultrasound, they are polypoidal with cystic areas and are vascular. The lesions are hyperintense on T2 sequences, isointense to the skeletal muscle on T1 sequences and show heterogenous enhancement. Surgery is the mainstay of treatment along with radiotherapy or chemotherapy depending on the site and the stage of the tumour. We report a case of botryoid variant of rhabdomyosarcoma involving the vagina and the urinary bladder.

Las neoplasias ginecológicas en niñas son raras. Representan menos del 5 % de todos los cánceres en pediatría. No existen estadísticas sobre la incidencia de tumores de vagina en esta etapa de la vida. Se presenta el caso de una niña de 9 meses con sangrado por genitales. La ecografía evidencia una masa sólida en vagina, y la vaginoscopia, un tumor friable. Presenta valores de α-fetoproteína elevados, por lo que se diagnostica tumor de saco vitelino, confirmado por biopsia. Se realiza tratamiento quimioterápico. A menos de 1 año del diagnóstico, se encuentra en remisión completa. Este caso resulta de interés no solo por la rareza, sino también porque el diagnóstico rápido de tumor de saco vitelino permite mejorar los resultados y la sobrevida de las pacientes
Gynecological neoplasms in girls are rare and represent only less than 5 % of all childhood tumors. There are no statistics on the incidence of vaginal tumors at this stage in life. We present a 9-month-old girl evaluated for genital bleeding. Ultrasound reveals a vaginal solid mass and vaginoscopy reports a friable tumor. AFP is elevated. A yolk sac tumor is confirmed by biopsy she receives chemotherapy. Within a year after diagnosis, she remains tumor-free. This is a case of interest, not only because of its rarity, but also because a rapid diagnosis of a yolk sac tumor improves outcomes and patient's survival rates.

Abstract Vaginal cancer is a rare entity. The evidence on its management resides mostly in clinical cases or small case series. Of the histological types, the most frequent is the squamous cell carcinoma, followed by adenocarcinoma. But what to do when identifying an even more infrequent sarcoma in a premenopausal woman? In this study, we describe the case of a 53-year-old woman presenting with metrorrhagia for two months, who was evaluated after an intense episode. A necrotic and ulcerative vaginal swelling was documented and then submitted to biopsy, which revealed a vaginal sarcoma. The patient was referred to radiation therapy with 50 Gy (aiming to control the symptoms and to cause tumor reduction for posterior pelvic exenteration with intraoperative radiotherapy) and developed an extra-pelvic metastization at the end of the treatment, which caused a fast negative outcome. Despite the initial poor prognosis, a chemo-irradiation or primary surgery regimen might have achieved (although with greater side effects) a better survival. This case-report entails a discussion about the strategies to manage vaginal sarcoma in advanced stage and in premenopausal women.
Resumo O cancro vaginal é uma doença rara. A evidência para a sua abordagem reside fundamentalmente em casos clínicos ou pequenas séries de casos. Dentre os tipos de cancro histológicos, o mais frequente é o carcinoma espinocelular, seguido do adenocarcinoma. Mas o que fazer em presença de um sarcoma ainda mais raro numa mulher pré-menopáusica? No presente estudo, descrevemos o caso de uma mulher de 53 anos apresentando metrorragia por dois meses, avaliada após um episódio intenso. Foi então documentada uma tumefacção vaginal necrótica e ulcerativa, submetida a biópsia, que revelou um sarcoma vaginal. A paciente foi encaminhada para radioterapia com50 Gy (comos objetivos de controlo da sintomatologia e de redução tumoral para posterior exenteração pélvica com radioterapia intraoperatória) e desenvolveu, ao final do tratamento, umquadro demestastização extra pélvica, que ocasionou um desfecho negativo rápido. Apesar do mau prognóstico inicial, um esquema de quimiorradiação ou cirurgia primária poderiam ter alcançado (ainda que com maiores efeitos laterais) uma maior sobrevivência. Este estudo de caso aborda uma discussão sobre as estratégias de abordagem do sarcoma vaginal em estádios avançados e na mulher pré-menopáusica.

RESUMEN El carcinoma primario de vagina representa 1 a 2% de los cánceres ginecológicos, siendo la diferenciación histológica neuroendocrina de células pequeñas extremadamente infrecuente, sólo se han reportado 28 casos en la literatura, describiéndose en orden de frecuencia en cérvix, endometrio, ovario, vagina y vulva. Se observa con más frecuencia en mujeres postmenopáusicas. Se presenta el caso de paciente femenino, de 39 años de edad, quien acude a la consulta por presentar secreción genital serohemática, fétida, de 1 mes de evolución, evidenciándose al examen físico lesión exofítica, friable, renitente, de aproximadamente 4 cm de diámetro, en tercio superior y cara posterolateral izquierda de vagina, por lo que se realiza biopsia excisional de dicha lesión, siendo el diagnóstico anatomopatológico carcinoma neuroendocrino de células pequeñas, grado histológico: 3. A propósito de este caso, se realiza una revisión del tema, haciendo hincapié en la importancia de la exploración ginecológica exhaustiva que incluya tomas de citologías y colposcopias periódicas, tomando en cuenta la vagina y así, realizar diagnóstico precoz en vista que el riesgo de carcinoma en dicha zona es infrecuente, mejorando el pronóstico y sobrevida de las pacientes.
ABSTRACT The primary carcinoma of the vagina represents 1 to 2 % of gynecologic cancers, being the histological differentiation neuroendocrine of small cells extremely infrequent, only 28 cases have been reported in the literature, describing in order of frequency: in the cervix, endometrium, ovary, vagina and vulva. It is most commonly seen in postmenopausal women. We present the case of a female patient, 39 years old, who comes to medical consult due to serohematic, fetid, genital discharge of 1 month of evolution, evidencing at physical examination an exophytic lesion, friable, renitent, with a diameter of approximately 4 cm, in the upper third and posterolateral left side of the vagina, for which an excisional biopsy of said lesion is performed, being the anatomopathological diagnosis neuroendocrine carcinoma of small cells, histological grade: 3. A bibliography reviewed was made, emphasizing the importance of exhaustive gynecological exploration with periodic cytology and colposcopy examinations, including the vagina for early diagnosis in view of carcinoma risk in this area is uncommon, improving the prognosis and survival of patients.

El rabdomiosarcoma es un tumor complejo y de gran malignidad que se origina en las células de la mesénquima embrionaria con capacidad para diferenciarse en células musculares esqueléticas. Este es el tumor maligno de tejido blando más frecuente. Representa aproximadamente 3,5 por ciento de los casos de cáncer en niños de 0 a 14 años de edad. Se presenta una paciente adolescente y virgen en la que se diagnostica histológicamente rabdomiosarcoma botrioide de la vagina. La presentación clínica del rabdomiosarcoma embrionario variedad botrioide es, en general, una masa que protruye por la uretra o el introito vaginal, o por la presencia de flujo fétido o sangrado vaginal en niñas menores de 2 años. En estas lesiones el apoyo diagnóstico con inmunohistoquímica es de vital importancia. El pronóstico de esta enfermedad está determinado por variables como el tamaño tumoral, órgano comprometido, edad del paciente, resultado quirúrgico (R0/R1) y presencia de metástasis. La evaluación médica multidisciplinaria precoz y oportuna permitirá siempre establecer un diagnóstico y tratamiento adecuados(AU)
Rhabdomyosarcoma is a complex and highly malignant tumor that originates in the cells of the embryonic mesenchyme with the ability to differentiate into skeletal muscle cells. This is the most common malignant soft tissue tumor. It represents approximately 3.5 percent of cancer cases in children from zero to 14 years of age. A case of a virgin adolescent patient is presented. A botryoid rhabdomyosarcoma of the vagina was diagnosed histologically. The clinical presentation of embryonic botryoid rhabdomyosarcoma variety is, in general, a mass that protrudes through the urethra or vaginal introitus, or the presence of fetid flow or vaginal bleeding in girls under 2 years. In these lesions, diagnostic support with immunohistochemistry is of vital importance. The prognosis of this disease is determined by variables such as tumor size, compromised organ, age of the patient, surgical result (R0 / R1) and presence of metastasis. Early and timely multidisciplinary medical evaluation will always allow an adequate diagnosis and treatment to be established(AU)

A neoplasia intraepitelial de vagina (NIVA) é uma condição pré-maligna rara do epitélio vaginal, sua incidência corresponde a 0,2 casos por 100.000 mulheres, classifica-se em NIVA I, II, III esta última tem um potencial de invasão de 9 a 12%. O diagnóstico é feito pela citologia, colposcopia, histopatologia. Todos os métodos terapêuticos tem uma taxa razoável de sucesso e a taxa de recorrência varia entre 10 e 42%. O tratamento pode ser: cirúrgico, ablativo, radioterápico, clínico e expectante. O excisional tem preferência por fornecer peça para análise histopatológica excluindo a doença invasiva apresentando as melhores taxas de sucesso entre 66% a 83% . A ablação é indicada quando a suspeita de invasão foi afastada e é a modalidade de eleição nas mulheres jovens, a eficácia varia entre 69 a 87%. A radiação tem uma taxa de sucesso entre 69 a 100%; porém, as complicações giram em torno de 36%. Pela sua praticidade o tratamento feito com os agentes tópicos tem ganhado espaço terapêutico na abordagem da NIVA. Não existe evidência científica quanto a melhor forma e o tempo de seguimento das mulheres com NIVA. Qualquer que seja a opção de tratamento utilizada um seguimento longo deve ser preconizado.(AU)
Vaginal intraepithelial neoplasia (VAIN) is an uncommon premalignant condition of the vaginal epithelium, its incidence is found to be 0.2 per 100.000 women, this condition is classificated in VAIN I, II and III, the lifetime risk of transformation to invasive carcinoma has been reported as 9 to 12%. The diagnosis was done by cytology, colposcopy and histology. All the therapeutics modalities have a successful cure rate and the recurrence ranges are between 10 to 42%. The treatment modalities are: excisional, ablative, radiotherapic, clinical and expectante. Excisional has preference as it could exclude invasion disease and has the best success rate, 66 to 83%. Ablation has preference in young women with no suspect of invasion, with efficacy ranging between 69 to 87%. The cure rate of radiotherapy is high as 69 to 100% but this modality has 36% morbidity rate. Treatment with topical agents constitutes a promising option in VAIN management. There is no scientific evidence of what kind follow-up is better. Whatever treatment modality is used long-term follow-up is essential.(AU)

Objetivo: actualizar los conocimientos disponibles sobre la neoplasia vaginal intraepitelial (VAIN) especialmente en el diagnóstico y tratamiento. Métodos: revisión de la literatura en Pubmed de los últimos 20 años, especialmente de los publicados desde 2005 hasta la actualidad y considerando sobre todo los ensayos clínicos aleatorizados. Resultados: su prevalencia real es desconocida, aunque es una patología rara generalmente en mujeres posmenopaúsicas. Su fisiopatología es similar a la neoplasia cervical intraepitelial, con el HPV como principal factor de riesgo, sobre todo el serotipo 16, pero su progresión a cáncer es menor. Un grupo importante es el de VAIN tras histerectomía, que supone el 48-70 por ciento del total de las VAIN. La colposcopia para el diagnóstico no es sencilla y se aconseja preparación con estrógenos en las pacientes menopáusicas y utilización de ácido acético y lugol para identificar las zonas sospechosas. Las tres opciones terapéuticas son la cirugía (excisional, láser, ultrasonidos), braquiterapia y tratamiento médico (imiquimod, 5-fluorouracilo, ácido tricloroacético). Se expone la técnica y las ventajas e inconvenientes de cada uno de ellos. Conclusión: aunque la VAIN es una entidad rara, es preciso tenerla en cuenta ante un diagnóstico de lesión citológica. Su diagnóstico a veces no es sencillo y el tratamiento dependerá del grado, la localización y el tamaño de la lesión y las circunstancias personales de la paciente. Se necesitan más ensayos aleatorizados que comparen la eficacia entre las distintas opciones terapéuticas y su repercusión en la calidad de vida de las pacientes.
Aims: update the knowledge about vaginal intraepithelial neoplasia (VAIN) with special emphasis on diagnosis and therapeutic management. Method: electronic search of Pubmed of all kinds of articles about the VAIN, for the last 20 years with special attention to those published from 2005 to the present and considering especially randomized clinical trials. Results: its prevalence is unknown, although it is a rare condition that usually occurs in postmenopausal women. The physiopathology is similar to cervical intraepithelial neoplasia, being HPV the main risk factor, particularly serotype 16, but its progression to cancer is lower. An important group is VAIN after hysterectomy, 48-70 percent of total VaIN. Colposcopy for the diagnosis is not easy and in patients with postmenopausal the preparation with local estrogen is necessary and use both of acetic acid and lugol to identify suspicious areas. The three treatment options are surgery (excisional, laser, ultrasound), brachytherapy and medical management (imiquimod, 5-fluorouracil, tricholoroacetic acid). The technique and the advantages and disadvantages of each are explained. Conclusion: although VAIN is rare, it must take it into account before a cytological diagnosis of dysplasia. Its diagnosis is sometimes not easy and the treatment depends on the extent, location and size of the lesion and the individual preferences of the patient. We need more randomized trials comparing different treatment options and also their impact on quality of life of patients.

La afectación primaria del tracto genital femenino de los linfomas no Hodgkin es poco frecuente (2 por ciento de los linfomas primarios extraganglionares). Los órganos más afectados son los ovarios seguidos del cérvix, siendo la localización endometrial y vaginal extremadamente rara. Presentamos el caso de una paciente de 44 años diagnosticada de linfoma primario de vagina, estadio IE A, con remisión completa tras tratamiento combinado quimioterápico y quirúrgico. Es importante tener presente estas raras aunque posibles localizaciones de linfomas para evitar que se puedan confundir con lesiones inflamatorias u otros tipos de tumores que nos lleven a un fracaso terapéutico.
Primary non-Hodgkin lymphomas rarely involve the female genital tract (2 percent of primary extranodal lym-phomas). The ovaries followed by the cervix are the most common affected sites while the involvement of the endometrium and vagina is extremely rare. We report the case of a 44 year old woman with a primary lymphoma of the vagina, stage IE A, with complete remission after combined chemotherapy and surgical treatment. These rare but possible locations must be kept in mind to avoid misdiagnosis with inflammatory lesions or other types of tumors which may lead us to a therapeutic failure.

Antecedentes: Los mioepiteliomas, son tumores poco frecuentes originados a partir de la proliferación de células mioepiteliales. La mayor parte localizados en las extremidades inferiores y en glándulas salivales. Existen ocasionales informes previos de MEP que involucren la vagina. Objetivo: Describir un caso de mioepitelioma localizado en vagina. Caso clínico: Embarazada de 29 años edad, quien presenta una masa vaginal de un año de evolución, localizada en el himen. El examen histopatológico muestra una lesión compuesta por células fusiformes con positividad inmunohistoquímica para vimentina, citoqueratinas (CK) AE1/ AE3, S100, CD10, receptores de estrógenos y progesterona, Bcl2 y calponina y negatividad para desmina, actina muscular especifica, actina de músculo liso y p63. Con los anteriores hallazgos se interpreta la lesión como un mioepitelioma primario vaginal. Conclusión: Los mioepiteliomas son tumores que requieren para su diagnostico, análisis con técnicas de inmunohistoquímica o ultraestructurales que permitan diferenciarlos de otros tumores.
Background: The myoepitheliomas are rare tumors arising from the proliferation of myoepithelial cells. Most tumors are located in the lower extremity and salivary glands. There have been only occasional myoepithelial neoplasms previously reported involving the vagina. Objective: Describe a case of myoepithelioma located in the vagina of a pregnant woman. Case report: A 29 years old pregnant female, who about 1 year prior has a vaginal mass, located in the hymen. At histopathological examination shows a mass composed of spindle cells with positivity immunohistochemical studies for vimentin, cytokeratin AE1/AE3, S100, CD10 and calponin and negative for desmin, actinmuscle specific (HHF35), smooth muscle actin and p63. With these findings it was established the diagnosis of myoepithelioma in the vagina. Conclusion: Myoepitheliomas are tumors requiring for diagnostic of immunohistochemistry or ultrastructural techniques that allow its differentiation from other tumors.

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.

Presentar un caso de mioma vaginal en una mujer de 52 años. Paciente asintomática, que acude a la consulta para control ginecológico. Se detecta una lesión en cara posterior de vaginal, sobre elevada e hiperpigmentada de aproximadamente 1 cm de diámetro, la cual fue extirpada con asa diatérmica; se envió el material para estudio histopatológico y el resultado fue leiomioma en vagina con hiperpigmentación melánica en la capa basal del epitelio. La paciente evolucionó bien
Vaginal myomas are very rare, generally asymptomatics, but could be presented with diverse symptoms regarding their localization and do not differ from their uterine counterparts. We present a clinic case of a 52 years old woman, asymptomatic, in whom a 1 cm sobreelevated, hyperpigmentated lesion was found on the posterior vaginal wall, which was removed with diathermical loop excision. Her pathological result was vaginal leiomyoma with melanical hyperpigmentation of the basal layer of the epithelium. We also present a literature revision

OBJETIVO: Aportamos un caso de un linfoma vaginal primario cuya primera manifestación fue un episo-dio de disuria y retención aguda de orina, con revisión bibliográfica. MÉTODOS: Paciente, 36 años. Consulta en urología por disuria inicial que desencadena un episodio de retención aguda de orina. La exploración muestra engrosamiento de la pared vaginal. Se biopsia obteniendo el diagnóstico de linfoma no Hodgkin difuso de células grandes B vaginal primario. RESULTADOS: Los linfomas primarios del tracto genital femenino son infrecuentes. La tercera localización en frecuencia es la vagina. La manifestación más frecuente es el sangrado vaginal. Rara vez son los síntomas urinarios el primer signo. Su diagnóstico es por anatomía patológica. El tratamiento de elección es la poliquimioterapia según el protocolo Rituximab-CHOP. CONCLUSIONES: El Linfoma vaginal es una patología infrecuente. Es raro que la primera manifestación sean síntomas urológicos, más todavía que se presente en forma de retención urinaria aguda
OBJECTIVE: We report a case of primary vaginal lymphoma. The clinical presentation was an episode of dysuria and acute urinary retention. We performed a bibliographic review. METHODS: Thirty-six year-old patient who consulted in the urology clinic for hesitancy that triggered an episode of acute urinary retention. Physical examination revealed thickening of the vaginal wall. Biopsy was performed and diagnosis of diffuse large B-cell primary vaginal non-Hodgkin's lymphoma was obtained. RESULTS: Primary lymphomas of the female genital tract are rare. The third most frequent location is vagina. The most common manifestation is vaginal bleeding. Urinary symptoms are rarely the first sign. Diagnosis requires a biopsy. The first choice for treatment is Rituximab- CHOP immuno-chemotherapy. CONCLUSIONS: Vaginal lymphoma is a rare disease. Unfrequently, the first clinical manifestations are urinary tract symptoms, and even less acute urinary retention
