RESUMO

El diagnóstico definitivo del cáncer de ovario precisa de confirmación histológica. En determinadas situaciones, para evitar la morbilidad de la resección quirúrgica, es posible hacer una biopsia guiada por ecografía para obtener el diagnóstico anatomopatológico. El objetivo de esta revisión sistemática fue evaluar la adecuación, fiabilidad, precisión y perfil de seguridad de la biopsia guiada por ecografía de masas ováricas. Siguiendo el modelo PRISMA 2020, se hizo una búsqueda bibliográfica en PubMed, Embase y Scopus y se recopilaron un total de 10.245 artículos, de los cuales 24 fueron finalmente incluidos. Los trabajos incluían de forma mayoritaria pacientes con tumores inoperables avanzados, pobre performance status y otros factores de mal pronóstico, con masas de contenido sólido y márgenes irregulares, generalmente accesibles por vía transvaginal. En la mayoría de los artículos las pacientes presentaban historia previa de malignidad o tumores inoperables en estadios avanzados. Las masas ováricas biopsiables se definían en la ecografía como malignas o potencialmente malignas, con la presencia destacada de un componente sólido o mixto con márgenes irregulares o heterogéneos. La técnica más utilizada en los estudios incluidos fue la biopsia con aguja gruesa o tru-cut, con altos valores de adecuación, fiabilidad, precisión y rendimiento, así como un buen perfil de seguridad y bajas tasas de complicaciones. En conclusión, la biopsia con aguja gruesa de las masas anexiales guiada por ecografía, en pacientes subsidiarios de tratamiento neoadyuvante, es una técnica con altas tasas de adecuación, fiabilidad, precisión y buen perfil de seguridad.(AU)


The definitive diagnosis of ovarian cancer requires histological confirmation. In certain situations, to avoid the morbidity of surgical resection, it is possible to perform an ultrasound-guided biopsy to obtain the pathological diagnosis. The aim of this systematic review was to assess the adequacy, reliability, accuracy, and safety profile of ultrasound-guided biopsy of ovarian masses. Following the PRISMA 2020 model, a bibliographic search was carried out in PubMed, Embase and Scopus, collecting a total of 10,245 articles, of which 24 were finally included. The studies mainly included patients with advanced inoperable tumors, poor performance status and other poor prognostic factors, with masses of solid content and irregular margins, generally accessible through the transvaginal route. In most of the articles, the patients had a previous history of malignancy or had inoperable tumors in advanced stages. Biopsiable ovarian masses were defined ultrasonographically as malignant or potentially malignant, mainly highlighting the presence of a solid or mixed component and irregular or heterogeneous margins. The most widely used technique in the included studies was core needle or tru-cut biopsy, presenting high values of adequacy, reliability, precision and performance, as well as a good safety profile with low complication rates. In conclusion, ultrasound-guided core needle biopsy of adnexal masses in patients eligible for neoadjuvant treatment is a technique with high adequacy, reliability, and precision rates, as well as a good safety profile.(AU)

RESUMO

Objectives: Evaluate the agreement between the clinical and histopathological diagnosis of oral lesions in patients submitted to biopsies. Identify the most frequent oral lesions and their correlation with age, gender, and anatomical location. Methods: A retrospective study of 368 pathological examinations collected between 2008 and 2018, corresponding to biopsies performed at the Clínica Universitária Egas Moniz. A detailed analysis of the histopathological reports attached to the patients' files was made and the variables gender, age, anatomical site, clinical diagnosis, and histopathological diagnosis was evaluated. Results: The most affected gender was female (55%); the most common age group was 61-70 years old; The most biopsied anatomical location was the gum (23.9%); the five most common pathological entities were fibroma(26.4%),root cyst(8.7%),oral lichen planus(7.6%), hemangioma (6.3%) and oral leukoplakia (6.0%). On agreement, 74.5% of the cases were concordant and 25.5% discordant. The most concordant lesions were Radicular Cyst (90.6%), Traumatic Injury (87.5%), Hemangioma (82.6%), Fibroma (82.5%) and Mucocele (82.5%). Conclusion: this study proves a significant level of agreement between clinical and histopathological diagnosis in this particular area, consistently obtained in a ten years period of time.

RESUMO

Monogenic autoinflammatory diseases are a heterogeneous emergent group of conditions that are currently under intensive study. We review the etiopathogenesis of these syndromes and their principal manifestations. Our aim is to propose a classification system based on the clinicopathologic features of typical skin lesions for routine clinical use in dermatology. Our focus is on diagnosis in pediatric practice given that this is the period when the signs and symptoms of these syndromes first appear. In Part 1 we discuss the course of urticaria-like syndromes, which include cryopyrin-associated periodic conditions and hereditary periodic fever syndromes. Pustular syndromes are also covered in this part. Finally, we review the range of therapies available as well as the genetic mutations associated with these autoinflammatory diseases.

RESUMO

OBJECTIVE: To evaluate the incidence and predictive factors for transient and permanent hypocalcemia and hypoparathyroidism following thyroidectomy. METHOD: We studied all the 162 patients that underwent thyroid surgery in the ENT department of the Centro Hospitalar Vila Nova Gaia/Espinho from January 2005 to December 2014. We reviewed pre-operative, 6h and 12h after surgery ionized calcium and PTH levels. All patients were reviewed and evaluated according to the following criteria: gender, age, thyroid function, histologic diagnosis of the specimen, surgery extension and presence or absence of hypoparathyroidism. RESULTS: There were 31 (19.1%) cases of transient hypoparathyroidism and 8 (5%) of permanent hypoparathyroidism. No significant difference was found for transient hypoparathyroidism when patients were analyzed by gender. However, all cases of permanent hypoparathyroidism were observed in female individuals. Comparing hemithyroidectomy with all other surgical procedures, we found that extension of surgery was a great predictor of transient (p=0.0001) and permanent (p=0.001) hypoparathyroidism. Diagnosis of malignancy was a strong predictor of transient hypoparathyroidism (p=0.002). It was also associated with permanent hypoparathyroidism, although differences did not reach statistical significance (p=0.096). CONCLUSION: Extension of surgery (total thyroidectomy) and diagnosis of malignancy are predictors of transient and permanent hypoparathyroidism.

RESUMO

BACKGROUND: Hidradenitis is a disorder where abscesses appear after the infection of the apocrine sweat glands. It is located normally in the axillae, groin, perineal region, and the scalp. CLINICAL CASE: A 37 year old male was referred by his GP to the General Surgery Department with axillary hidradenitis which had evolved over the years. The physical examination shows signs of hidradenitis in both axillae, with a noticeable suppurative hidradenitis in the right armpit. En bloc extirpation was performed to remove the whole affected area. The pathological examination revealed a cutaneous leishmaniasis. Subsequently, fucidin was administered topically, as well as local infiltrations of one millilitre of Glucantime™. DISCUSSION: Hidradenitis normally appears in intertriginous areas and its manifestation is accompanied by recurrent subcutaneous nodules. The incidence rate in females is three times higher than in males. The isolated Hidradenitis caused by Leishmania is a rare condition presented only in endemic areas or in immunocompromised patients, such as HIV-infected patients. Clinical manifestations can be different and the diagnosis can be confirmed through haematoxylin-eosin. The main pattern displays a disorganised granuloma without necrosis. Systemic or topical treatment can be applied. Immunotherapy treatment is the most common. CONCLUSIONS: Hidradenitis caused by Leishmania in HIV-negative patients is a rare condition. Therefore it is important to perform a good histological diagnosis and to administer the right treatment.

RESUMO

Introducción: el cáncer de esófago se considera una entidad poco frecuente, con comportamiento agresivo y curso clínico progresivo. El objetivo de este trabajo es caracterizar clínico y patológicamente a los pacientes con cáncer esofágico diagnosticados en el hospital estudiado. Materiales y Métodos: se realizó un estudio descriptivo, longitudinal y prospectivo en 35 pacientes atendidos en el Servicio de Gastroenterología del Hospital Militar Docente Dr Mario Muñoz Monroy, en la ciudad de Matanzas, desde enero del 2012 hasta diciembre del 2013, con el diagnóstico endoscópico e histológico de cáncer de esófago. Se analizaron variables como grupo etáreo, sexo, factores de riesgo, manifestaciones clínicas, tiempo de aparición de los síntomas, tipo endoscópico y tipo histológico que fueron representadas en tablas por frecuencias absolutas y relativas.Resultados: predominó el sexo masculino (85,7 por ciento), con edades mayores de 60 años (88,6 por ciento). La dieta inadecuada, la ingestión de alcohol y tabaquismo fueron factores de riesgo predominantes. La disfagia fue el principal motivo de consulta en dichos pacientes. Todos los casos se diagnosticaron entre los 3 y 6 meses del inicio de los síntomas. endoscópicamente predominó el tipo polipoide o vegetante (63,2 por ciento). La mayoría de los casos estuvieron localizados en el tercio medio esofágico (34,2 por ciento). El carcinoma de células escamosas fue el más frecuente histológicamente (52,6 por ciento)(AU)

RESUMO

Introducción: La laringoscopía directa (LD) se considera indispensable en el estudio del cáncer de laringe, tanto para precisar la extensión como para tomar biopsia. Objetivo: Demostrar que el resultado de biopsias tomadas por videonasofibroscopía (VFC) en cáncer de laringe es equivalente al de la biopsia definitiva. Material y método: Revisión de fichas de 53 pacientes del Servicio de Otorrinolaringología HBLT con sospecha de cáncer de laringe con biopsia realizada por VFC y definitiva, durante julio 2007 a diciembre 2011. Resultados: La muestra se compone mayormente por hombres de edad promedio 66 años, con consumo de tabaco en 63% y alcohol en 55,3%. Con correlación positiva entre biopsias para cáncer en 32 pacientes, 8 falsos negativos y 2 falsos positivos. Todas las muestras con cáncer fueron carcinoma escamoso. El 55% moderadamente diferenciado. Los falsos negativos no se encontraban en un estadio en particular. La sensibilidad de biopsia por VFC fue de 0,8 y la especificidad de 0,85. El LR fue de 5,2. Conclusión: Debe incluirse como parte del estudio ambulatorio ante la sospecha, ya que orienta el tratamiento inicial. Permite realizar la LD en el acto del tratamiento quirúrgico, así como evitarla en pacientes sin opción curativa quirúrgica, vía aérea difícil o alto riesgo anestésico.


Introduction: Direct laryngoscopy (DL) is considered essential in the study of the larynx cancer, both to specify local extension and in order to perform a biopsy. Aim: Show that the result of biopsies taken by videolaringoscopy (VL) in larynx cancer is equivalent to the definitive biopsy. Material and methods: Review of 53 patients charts of HBLT Otorhinolaryngology Service with suspected larynx cancer where the biopsy is performed by VL, during July 2007 to December 2011. Results: The patients included, are characterized by being mostly men with an average age of 66 years, with tobacco consumption by 63% and alcohol by 55.3%. There was a congrunence between positive biopsies for cancer in 32 patients, 8 false negatives and 2 false positives. All samples which tested positive for cancer were squamous cell carcinoma, 55% moderately differentiated. The patients that had false-negative results were not in a particular stage. The sensitivity was 0.8 and the specificity 0.85. The LR was 5.2. Conclusion: VL must be included as part of the ambulatory studies orienting the initial treatment when larynx cancer is suspected. VL allows to perform the DL in the act of surgical treatment, and avoid it in patients without surgical curative option, difficult airway or high anesthetic risk.

RESUMO

Introducción: en Cuba, el cáncer colorrectal constituye la tercera causa de mortalidad después del cáncer de pulmón y próstata. Se realizó este trabajo con el objetivo de caracterizar endoscópica e histológicamente a los pacientes con cáncer colorrectal diagnosticados en el hospital estudiado. Métodos: se realizó un estudio descriptivo con 76 informes de videocolonoscopia realizadas en el Hospital Universitario Clínico Quirúrgico Comandante Faustino Pérez Hernández, desde junio de 2006 a junio de 2010, lo que constituyó el universo de trabajo. Se excluyeron los informes donde el proceder no pudo realizarse completo o no presentaban el resultado histológico de la lesión diagnosticada. Se analizaron las variables: grupo etario, sexo, localización de la lesión, aspecto endoscópico, variedad histológica y presencia de lesiones sincrónicas, estas fueron representadas en tablas y gráficos por frecuencias absolutas y relativas. Resultados: el grupo etario más frecuente fue de 50 a 64 años, con predominio del sexo masculino (56,6 %). La localización más frecuente fue en el colon rectosigmoide (34,2 %). El aspecto endoscópico más encontrado fue el ulcerado (63,2 %). La variedad histológica más frecuente fue el adenocarcinoma moderadamente diferenciado (52,6 %), predominando la presencia de adenomas sincrónicos (43,4 %). Conclusiones: los pacientes mayores de 50 años siguen siendo los más propensos a padecer de cáncer colorrectal. El aspecto endoscópico ulcerado, localizado en el rectosigmoide, histológicamente diagnosticado como adenocarcinoma moderadamente diferenciado, responden a un diagnóstico tardío.


Introduction: in Cuba, colorectal cancer is the third cause of mortality after lung and prostate cancer. We developed our work with the objective of arriving to an endoscopic and histological characterization of the patients with colorectal cancer diagnosed in the mentioned hospital. Method: we carried out a descriptive study with 76 reports of videocolonoscopies made in the Teaching Clinico-surgical Hospital Comandante Faustino Pérez Hernández, from June 2006 to June 2010, and that was the universe of our work. We excluded the reviews where the procedure could not be completely finished or that were lacking of the diagnosed lesion histological result. We analyzed the following variables: age group, gender, lesion localization, endoscopic aspect, histological variety and presence of synchronic lesions. They were represented in tables and charts showing the absolute and relative frequencies. Results: the most frequent age group was the one comprehending people aged 50-64 years old, with predomination of the male gender (56,6 %). The most frequent localization was the rectosigmoid colon (34,2 %). The most common endoscopic aspect we found was the ulcerated one (63,2 %). The most frequent histological variety was the moderately differenced adenocarcinoma (52,6 %), predominating the synchronic adenomas (43,4 %). Conclusions: patients elder 50 years old are still the ones who tend more of suffering from colorectal cancer. The ulcerated endoscopic aspect, found in the rectosigmoid colon, histologically diagnosed as moderately differentiated carcinoma, is the result of a late diagnosis.

RESUMO

EL DIAGNOSTICO HISTOLÓGICO DE LA INFECCIÓN por Helicobacter pylori (Hp) puede ser difícil, principalmente en casos con pocos microorganismos. Nuestro objetivo fue determinar si hay diferencias significativas en la frecuencia del diagnóstico de la infección por Hp entre patólogos que laboran en Medellín. MATERIALES Y MÉTODOS: revisamos todos los informes de biopsias gástricas de ocho patólogos durante un año. Excluimos las biopsias con metaplasia, atrofia, displasia o carcinoma. Registramos la edad del paciente, la presencia o ausencia de Hp y el patólogo que estudió la biopsia. Calculamos el porcentaje de casos con la infección y el porcentaje por patólogo. Finalmente, comparamos estos porcentajes para determinar las diferencias. RESULTADOS: incluimos 2.023 casos en el presente estudio. El número de biopsias evaluadas por patólogo fue de 252,9 ± 154,9 (rango: 102-445). La edad promedio de los pacientes fue de 43,5 ± 15,1 años (rango 12-90). En 1.034 casos (51,1%) se diagnosticó la infección. La tasa de positividad para Hp por patólogo tuvo un rango de 38,8 a 71,1%, con una media de 51,1% ± 8,7% (p < 0,001). CONCLUSIÓN: hay una variabilidad significativa en la frecuencia de infección por Hp de acuerdo con el patólogo que interpreta la biopsia. Este resultado sugiere la necesidad de estudiar más a fondo la situación, buscando mayor homogeneidad de conceptos y criterios para el diagnóstico de esta infección y, posteriormente, mayor refinamiento en la graduación de su gravedad.


Histopathologic diagnosis of Helicobacter pylori (Hp) infection is not necessarily easy, and reproducibility is not perfect. Our aim was to determine differences in the frequency of Hp infection according to the pathologists interpreting gastric biopsies in Medellín ( Colombia ). MATERIAL AND METHODS: All gastric biopsy reports of eight pathologists during one year were reviewed. We excluded cases with intestinal metaplasia, atrophy, dysplasia or carcinoma. We registered patient age, positivity or negativity for H. pylori, and pathologist. We determined the percentage with H. pylori infection and the percentage of each pathologist in order to determine differences. RESULTS: 2.023 cases were included. Each pathologist evaluated a mean of 252.9 ± 154.9 cases (range: 102-445). Patients were 43.5 ± 15.1 years-old (range: 12-90). H. pylori was diagnosed in 1.034 cases (51.1%). The range of positivity according to the pathologist was 38.8-71.1%; mean 51.1% ± 8.7% (p < 0,001). CONCLUSION: Among pathologists, there is a significant variability in the frequency of diagnosis of H. pylori infection. This result suggests the need to achieve greater homogeneity of concepts and criteria for the diagnosis of this infection, and of its severity.
