Introduction:Pancreaticopleural fistula is a rare complication of chronic pancreatitis. Objective:To describe pancreaticopleural fistula due to chronic pancreatitis and perform an extensive review of literature on this topic. Methods:Comprehensive narrative review through online research on the databases Medline and Lilacs for articles published over the last 20 years. There were 22 case reports and four case series selected. Results:The main indication for surgical treatment is the failure of clinical and/or endoscopic treatments. Surgery is based on internal pancreatic drainage, especially by means of pancreaticojejunostomy, and/or pancreatic resections. Conclusion:Pancreaticopleural fistula is a rare complication of chronic pancreatitis and the Frey procedure may be an appropriate therapeutic option in selected cases when clinical and endoscopic treatments are unsuccessful.

CONTEXT: Pancreatic metastases from primary malignant tumors at other sites are rare, constituting about 2% of the neoplasms that affect the pancreas. Pancreatic metastasis from breast cancer is extremely rare and difficult to diagnose, because its clinical and radiological presentation is similar to that of a primary pancreatic tumor. CASE REPORT: A 64-year-old female developed a lesion in the pancreatic tail 24 months after neoadjuvant therapy, surgery and adjuvant radiation therapy for right-side breast cancer (ductal carcinoma). She underwent distal pancreatectomy with splenectomy and left adrenalectomy, and presented an uneventful outcome. The immunohistochemical analysis on the surgical specimen suggested that the lesion originated from the breast. CONCLUSION: In cases of pancreatic lesions detected in patients with a previous history of breast neoplasm, the possibility of pancreatic metastasis should be carefully considered.

RESUMO Objetivo: estudar a prevalência do câncer de vesícula biliar em pacientes submetidos à colecistectomia no Hospital de Clínicas da Universidade Estadual de Campinas. Métodos: estudo de prevalência retrospectivo a partir da análise de laudos de espécimes histopatológicos de pacientes submetidos à colecistectomia, no período de janeiro de 2010 a maio de 2015. Resultados: foram analisados 893 laudos de pacientes submetidos à colecistectomia, dos quais 144 de urgência e 749 eletivas (16,2% e 83,8%, respectivamente). Segundo o sexo, 72,8% correspondiam ao feminino e 27,2%, ao masculino. Em 12 pacientes (1,3%) foi evidenciado o diagnóstico de adenocarcinoma de vesícula biliar e, em um (0,1%), o diagnóstico de linfoma não Hodgkin. Dos 13 pacientes com neoplasia, sete (53,8%) apresentaram colecistolitíase associada. Em dois doentes (15,3%) foi constatado pólipo de vesícula biliar. Sete (53,8%) doentes foram operados com a hipótese diagnóstica de neoplasia de vesícula biliar. Conclusão: a prevalência do adenocarcinoma de vesícula biliar no presente estudo foi semelhante à dos estudos ocidentais e o principal fator de risco foi a colecistolitíase, seguido pela presença de pólipos de vesícula biliar.
