Introdução: O carcinoma basocelular (CBC) de vulva é uma condição rara que corresponde a menos de 0,4% dos casos de CBC e de 2% a 4% das neoplasias de vulva. O CBC de vulva é mais comum entre mulheres brancas, multíparas e na pósmenopausa, especialmente na sétima década de vida. O objetivo é relatar um caso de CBC de vulva no qual discutiram-se os aspectos do diagnóstico e tratamento. Relato de Caso: Mulher de 63 anos de idade, G1P1A0, chega ao consultório em janeiro de 2022 para tratamento de lesão persistente em vulva. Realizou-se biópsia incisional que mostrou tratar-se de provável carcinoma basocelular nodular com invasão da derme. A paciente submeteu-se a uma ressecção do tumor com margens macroscópicas livres e sutura primária. A cirurgia não teve complicações no pré-operatório e no pós-operatório. O histopatológico da peça cirúrgica mostrou tratar-se de carcinoma basocelular nodular com área irregular, plana, branco, medindo 0,7x0,4cm, com as margens laterais distando 7,0 e 5,0mm e profundas, 5,9mm; todas livres. Conclusão: O caso relatado é raro, tendo sido o tratamento de ressecção cirúrgica do CBC de vulva com margens bem-sucedido. Catorze meses após a cirurgia, a paciente encontra-se sem evidências de recidiva local ou regional.

Introduction: Basal cell carcinoma (BCC) of the vulva is a rare condition that accounts for less than 0.4% of BCC cases and 2% to 4% of vulvar neoplasms. BCC of the vulva is more common among white, multiparous and postmenopausal women, especially in the seventh decade of life. The aim is to report a case of BCC of the vulva in which aspects of diagnosis and treatment were discussed. Case report: A 63-year-old woman, G1P1A0, arrives at the office in January 2022 for treatment of a persistent lesion on her vulva. An incisional biopsy was performed and showed that it was likely nodular basal cell carcinoma with invasion of the dermis. The patient underwent tumor resection with free macroscopic margins and primary suture. The surgery had no complications preoperatively or postoperatively. The histopathology of the surgical specimen showed that it was a nodular basal cell carcinoma with an irregular, flat, white area, measuring 0.7x0.4cm, with the lateral margins 7.0 and 5.0mm apart and 5.9mm deep; all free. Conclusion: The reported case is rare, with surgical resection of BCC of the vulva with margins being successful. Fourteen months after surgery, the patient has no evidence of local or regional recurrence.

Tumor filoide borderline gigante e recidivante: ressecção e reconstrução da mama / Recurrent giant borderline phyllodes tumor: resection and breast reconstruction

O tumor filoide é uma neoplasia fibroepitelial rara que representa 0,3 a 1% de todas as neoplasias mamárias. De acordo com a classificação histopatológica, 12 a 26% são do tipo borderline e aproximadamente 15% desses tumores recorrem após excisão cirúrgica. O tratamento recomendado para todos os tipos de tumor filoide é a excisão cirúrgica, e no caso de tumores gigantes o tratamento deve ser multidisciplinar. Apresentamos o caso de uma mulher de 46 anos com tumor filoide na mama esquerda que recorreu 4 anos após a excisão cirúrgica. O estudo anatomopatológico qualificou-o como tumor gigante e o estudo histopatológico relatou tumor filoide borderline. Foi submetida a excisão cirúrgica com mastectomia esquerda e reconstrução mamária com retalho de grande dorsal mais enxerto de gordura. A paciente apresentou evolução favorável sem recidiva. Concluindo, o tumor filoide gigante borderline recorrente é raro e seu manejo cirúrgico representa um desafio tanto na excisão quanto na reconstrução mamária.

Phyllodes tumor is a rare fibroepithelial neoplasm that represents 0.3 to 1% of all breast neoplasms. According to histopathologic classification, 12 to 26% are borderline type and approximately 15% of these tumors recur after surgical excision. The recommended treatment for all types of phyllodes tumor is surgical excision, and in the case of giant tumors the treatment should be multidisciplinary. We present the case of a 46-yearold woman with a phyllodes tumor in the left breast that recurred 4 years after surgical excision. The anatomopathological study qualified it as a giant tumor and the histopathological study reported a borderline phyllodes tumor. She underwent surgical excision with left mastectomy and breast reconstruction by means of a latissimus dorsi flap plus fat graft. The patient presented a favorable evolution without recurrence. In conclusion, the recurrent giant borderline phyllodes tumor is rare and its surgical management represents a challenge both in breast excision and reconstruction.

Tumor metastásico en tejido blando a nivel del sacro secundario a carcinoma de células claras de riñón. Reporte de caso / Metastatic tumor in soft tissue at the level of the sacrum secondary toclear cell carcinoma of the kidney. A case report

Introducción. El cáncer de riñón es la undécima neoplasia maligna más común en los Estados Unidos Mexicanos. El carcinoma de células claras de riñón (CCR) es considerado la estirpe más frecuente y representa el 2-3 % de todos los cánceres a nivel mundial. En el contexto de la enfermedad metastásica, por lo general se identifica un tumor renal primario y las metástasis se localizan en pulmón, hueso, hígado, cerebro y, raramente, en tejidos blandos. Los pacientes con metástasis a tejidos blandos no tienen síntomas en las etapas iniciales y generalmente se identifican sólo cuando las lesiones aumentan de tamaño o durante el estudio de la pieza de resección quirúrgica. Caso clínico. Se presenta el caso de una paciente en la séptima década de la vida, con una metástasis en tejidos blandos de la región sacra, de 10 años de evolución posterior a una nefrectomía secundario a CCR. Resultados. Hallazgos clínicos e imagenológicos de un tumor bien delimitado. Se realizó resección quirúrgica de la lesión, bajo anestesia regional, con extirpación completa. Conclusión. Se recomienda que los pacientes con un sitio metastásico resecable y solitario sean llevados a resección quirúrgica con márgenes libres, como fue el caso de nuestra paciente, por su fácil acceso y ser una lesión única. En el CCR, además de su tratamiento quirúrgico inicial, es indispensable una estrecha vigilancia con examen físico e imágenes transversales, para detectar la presencia de metástasis y con ello evitar tratamientos tardíos.

Introduction. Kidney cancer is the eleventh most common malignancy in the United States of Mexico. Carcinoma renal cell (CRC) is considered the most frequent type and represents 2-3% of all cancers worldwide. In the setting of metastatic disease, a primary renal tumor is usually identified, and metastases are located in the lung, bone, liver, brain, and rarely in soft tissue. Patients with soft tissue metastases do not have symptoms in the initial stages and are generally found only when the lesions increase in size or during the study of the surgical resection piece. Clinical case. In this case, we report a female patient in the seventh decade of life with a soft tissue metastasis located in the sacral region, 10 years after a nephrectomy secondary to CRC. Results. Clinical and radiological findings of a well-defined tumor. Surgical resection of the lesion is performed under regional anesthesia with complete excision. Conclusions. It is recommended that patients with a resectable and solitary metastatic site be candidates for surgical resection with free margins, as was the case with our patient due to its easy access and single lesion. In CRC, in addition to its initial surgical treatment, close surveillance with physical examination and cross-sectional images is essential to monitor the presence of metastases and thus avoid late treatments.

Manejo y resultados de pacientes con diverticulitis aguda: experiencia de cinco años en el Hospital San Vicente Fundación / Management and results of patients with acute diverticulitis. Five year-experience at the San Vicente Fundación Hospital

Introducción. Los datos epidemiológicos de la diverticulitis en Colombia son limitados. El objetivo de este artículo fue caracterizar una población que ingresó con diverticulitis aguda al Hospital Universitario San Vicente Fundación, un centro de referencia de la ciudad de Medellín, Colombia, para analizar la presentación y comportamiento de la enfermedad en la población local, con estadísticas propias y desenlaces de la enfermedad en los últimos años. Métodos. Estudio observacional retrospectivo, descriptivo, entre enero de 2015 y diciembre de 2019. Se hizo un estudio exploratorio uni-, bi- y multivariado de factores de riesgo para fallo en el tratamiento y la mortalidad. Resultados. Se incluyeron 103 pacientes. Se presentó principalmente en mujeres y la edad promedio fue de 65 años. La diverticulitis Hinchey Ia fue la más frecuente (41,7 %) y el manejo médico fue exitoso en todos los casos, mientras que en las tipo III y IV, todos se manejaron de forma quirúrgica, con tasas de éxito entre el 50 y el 64 %. La presencia de signos de irritación peritoneal al examen físico, el recuento de leucocitos y la PCR, el ingreso a la Unidad de Cuidados Intensivos y la mortalidad aumentaron de forma directamente proporcional con el estadio de Hinchey. Conclusiones. Existe una relación directamente proporcional entre la clasificación de Hinchey y los signos de respuesta inflamatoria clínicos y paraclínicos, la necesidad de manejo quirúrgico, la estancia en la Unidad de Cuidados Intensivos y la mortalidad.

Introduction. Epidemiological data on diverticulitis in Colombia are limited. The objective of this article was to characterize a population that was admitted with acute diverticulitis to the San Vicente Fundación University Hospital, a reference center in the city of Medellín, Colombia, to analyze the presentation and behavior of the disease in the local population, with its own statistics, and outcomes of the disease in recent years. Methods. Retrospective descriptive observational study between January 2015 and December 2019. An exploratory uni-, bi- and multivariate study of risk factors for treatment failure and mortality was performed. Results. A total of 103 patients were included. The most frequent Hinchey classification was Ia (41.7%). It occurs mainly in women, mean age 65 years. Hinchey Ia diverticulitis is the most frequent and medical management is successful in 100% of cases; while in III and IV, 100% were managed surgically with success rates between 50 and 64%. The presence of peritoneal signs on physical examination, leukocyte count and CRP, ICU admission and mortality increased directly proportional with Hinchey stage. Conclusions. There is a directly proportional relationship between Hinchey staging with clinical and paraclinical signs of inflammatory response, need for surgical management, ICU stay and mortality.

Resultados Perinatais e Seguimento em Longo Prazo de Tumores Cardíacos Fetais: Estudo de Coorte Histórica de 30 Anos / Perinatal Results and Long-Term Follow-Up of Fetal Cardiac Tumors: A 30-Year Historical Cohort Study

Resumo Fundamento: Seguimento de coorte retrospectiva de 30 anos que se aproxima da história natural dos tumores cardíacos diagnosticados no feto uma vez que nenhum caso foi submetido à interrupção da gestação. Objetivo: Avaliar a morbidade e mortalidade perinatal e em longo prazo em fetos com diagnóstico de tumor cardíaco. Como objetivo secundário avaliar os fatores que influenciaram os resultados perinatais e pós-natais. Método: Estudo de coorte retrospectiva envolvendo 74 gestantes com diagnóstico ecocardiográfico fetal de tumor cardíaco acompanhadas em dois serviços de referência no período de maio de 1991 a novembro de 2021. Foi realizada análise descritiva dos dados por meio de frequências absolutas (n) e relativas (%), mediana e intervalos interquartis. Para avaliar a associação entre as características ecocardiográficas e as manifestações clínicas com os resultados perinatais e pós-natais, foi aplicado o teste exato de Fisher. O cálculo da sobrevida global foi realizado pelo método de Kaplan-Meier e a comparação de curvas pelo teste de log-rank. O tempo de seguimento, calculado em meses, foi definido a partir da data de alta do hospital à data do status atual (vivo/censura ou óbito). O nível de significância considerado foi de 5% (p<0,05). Resultados: o rabdomioma é o tipo mais frequente (85%) de tumor cardíaco; apresenta alta morbidade (79,3%) e mortalidade geral de 17,4%; a presença de hidropisia fetal preditiva de óbito. Conclusão: A presença de hidropisia fetal teve impacto na mortalidade, sendo fator importante para aconselhamento e estabelecimento de prognóstico. A maioria dos óbitos ocorrem antes da alta hospitalar.

Abstract Background: This was a 30-year retrospective cohort study that approximates closely to the natural history of cardiac tumors diagnosed in the fetus, since there was no case of pregnancy interruption Objective: To assess morbidity and mortality in the perinatal period and at long term in fetuses diagnosed with cardiac tumor. Our secondary objective was to assess the evaluating factors of perinatal and postnatal results. Methods: This was a retrospective cohort study with 74 pregnant women with an echocardiographic diagnosis of fetal cardiac tumor at two referral centers between May 1991 and November 2021. A descriptive analysis was performed, and data were expressed as absolute (n) and relative (%) frequencies, median and interquartile range. Fisher's exact test was used to evaluate the association of echocardiographic characteristics and clinical manifestations with perinatal and postnatal results. Global survival was calculated using the Kaplan-Meier method and the curves were compared by the log-rank test. The time of follow-up, calculated in months, corresponded to the time elapsed from hospital discharge to current status (survived/ censoring or death). The level of significance was set at 5% (p<0.05). Results: Rhabdomyoma is the most common type of cardiac tumor (85%), with a high morbidity (79.3%) and overall mortality of 17.4%. The presence of fetal hydrops was a predictor of death. Conclusion: The presence of fetal hydrops had an impact on mortality, and hence is an important factor in counselling and determining the prognosis. Most deaths occurred before hospital discharge.

Concordance of acid-fast stain result and histopathologic vs clinical diagnosis of leprosy: A three-year retrospective study in a Tertiary Government Hospital and Sanitarium in the Philippines

Objectives@#In the Philippines, there has been a lack of information on the concordance between classifications of Hansen’s disease or leprosy clinically, histopathologically, and with AFS results. The study ultimately aimed to determine the concordance between the clinical diagnosis, histopathological results, and AFS results of patients with leprosy seen at the Dr. Jose N. Rodriguez Memorial Hospital and Sanitarium (DJNRMHS). @*Methods@#This is a descriptive, retrospective, single-center study conducted at the DJNRMHS, a tertiary government hospital and one of the last remaining sanitaria in the country located in northern Metro Manila in the Philippines. The study reviewed and included all the patient records from the years 2017-2019 which included skin biopsy results and slit-skin smear with AFS. Leprosy patients were then classified based on the following classifications: World Health Organization (WHO) and Ridley-Jopling classifications; and the concordance of clinical diagnosis vs the histopathologic findings and clinical diagnosis vs AFS results were determined using kappa testing.

Role of exosomes in intrahepatic cholangiocarcinoma / 临床肝胆病杂志

Intrahepatic cholangiocarcinoma （ICC） is a special type of liver cancer with atypical clinical symptoms in the early stage， and most patients are already in the advanced stage at the time of initial diagnosis. Due to a lack of effective molecular markers and treatment options， ICC patients tend to have an extremely low five-year survival rate. Exosomes are vesicles secreted by cells that contain proteins， RNA， and lipids， and they are important carriers of intercellular communication. Recent studies have shown that exosomes play a crucial role in the development and progression of ICC， and this article reviews the role and mechanism of exosomes in the diagnosis and treatment of ICC and looks into the future treatment prospect and potential clinical application of exosomes.

A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups， and the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups； the Fisher’s exact test was used for comparison of categorical data between groups. ResultsFor the 30 patients with HLD， the male/female ratio was 3∶1， and the mean age was 46.13±5.88 years； the patients with positive Kayser-Fleischer ring of the cornea accounted for 43.33%， and the patients with liver cirrhosis accounted for 66.67%. There were significant differences between the three groups in globulin， albumin/globulin ratio， alanine aminotransferase， prothrombin time， international normalized ratio， and activated partial thromboplastin time （F=5.893， 4.513， 4.424， 5.029， 5.248， and 4.942， all P<0.05）. ConclusionMost patients are male among the patients diagnosed with HLD after 35 years of age， with the main clinical types of mixed type and liver type， and such patients tend to have poor liver and coagulation functions. For unexplained liver function abnormalities and liver cirrhosis in this age group， the indicators such as serum ceruloplasmin and urinary copper should be screened as early as possible， and liver and kidney function and coagulation function should be monitored.

Application value of liver/spleen CT value， controlled attenuation parameter， and magnetic resonance imaging-proton density fat fraction in chronic hepatitis B patients with hepatic steatosis / 临床肝胆病杂志

ObjectiveTo investigate the application value of liver/spleen CT value （CTL/S）， controlled attenuation parameter （CAP）， and magnetic resonance imaging-proton density fat fraction （MRI-PDFF） in chronic hepatitis B （CHB） patients with hepatic steatosis. MethodsA retrospective analysis was performed for the clinical data of 213 CHB patients who underwent liver CT， CAP， and MRI-PDFF examinations in Affiliated Hospital of Yan’an University from October 2018 to December 2022. According to MRI-PDFF， the 213 patients were divided into CHB group with 111 patients （MRI-PDFF<5%） and CHB+hepatic steatosis group with 102 patients （MRI-PDFF≥5%）， among whom there were 69 patients with mild hepatic steatosis and 33 patients with moderate to severe hepatic steatosis. The independent-samples t test was used for comparison of normally distributed continuous data between groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups. The Bland-Altman plot was used to evaluate the consistency in MRI-PDFF measurement between two physicians. The Spearman’s correlation coefficient was used to analyze the correlation between CTL/S and MRI-PDFF and between CAP and MRI-PDFF. The receiver operating characteristic （ROC） curve was plotted and the area under the ROC curve （AUC） was calculated to investigate the value of CTL/S and CAP in the diagnosis of different degrees of hepatic steatosis， and the DeLong test was used to compare the AUCs of the two radiological examinations. ResultsMRI-PDFF had relatively high repeatability and stability in CHB patients. There is a significant negative correlation between CTL/S and MRI-PDFF （r=-0.800， P<0.001） and a significant positive correlation between CAP and MRI-PDFF （r=0.692， P<0.001）. Both CTL/S and CAP had a relatively high accuracy in the diagnosis of hepatic steatosis in CHB patients， with an AUC of 0.951 and 0.902， respectively， and CTL/S had a better accuracy than CAP （P<0.05）. In the diagnosis of mild and moderate-to-severe hepatic steatosis， CTL/S had an AUC of 0.921 and 0.895， respectively， and CAP had an AUC of 0.859 and 0.825， respectively， suggesting that CTL/S had a slightly higher diagnostic efficiency than CAP. ConclusionMRI-PDFF has high repeatability and stability in CHB patients， and CTL/S and CAP have a high diagnostic value for different degrees of hepatic steatosis in CHB patients.

An excerpt of Asia-Pacific Association for the Study of the Liver guidelines on management of ascites in liver disease （2023） / 临床肝胆病杂志

Asia-Pacific Association for the Study of the Liver published the guidelines on management of ascites in liver disease in May 2023， which introduces the diagnosis， differential diagnosis， and treatment of ascites， hyponatremia， hepatic hydrothorax， and hepatorenal syndrome in patients with liver cirrhosis and acute-on-chronic liver failure. This article summarizes the main recommendations in the guidelines， so as to provide a reference for the treatment of ascites in patients with liver diseases in China.

Research advances in the diagnosis and treatment of hepatic vein occlusion-type Budd-Chiari syndrome / 临床肝胆病杂志

Budd-Chiari syndrome is a rare liver vascular disease and can be classified into hepatic vein occlusion type， inferior vena cava occlusion type， and mixed type according to the location of hepatic outflow tract obstruction. This article reviews the hepatic vein occlusion type from the aspects of epidemiology， subtypes， clinical diagnosis， and treatment strategies.
