title: Metastatic testicular tumor presenting as a scrotal hydrocele: An initial manifestation of pancreatic adenocarcinoma.
abstract: Metastatic pancreatic adenocarcinoma involving the testis is a rare condition with a poor prognosis. The current study describes the case of a 69-year-old male who presented with a painful swelling of the left scrotum. Scrotal ultrasonography revealed hydroceles in the scrotal sacs, with the left one being larger in size. The patient underwent left hydrocelectomy and was eventually diagnosed with metastatic adenocarcinoma. Abdominal computed tomography, which was performed to detect the primary cancer, showed a pancreatic tail carcinoma with liver and multiple lymph node metastases, and peritoneal carcinomatosis. The patient received gemcitabine-based chemotherapy but resulted in progressive disease. This case shows that in a patient in whom a primary testicular tumor is unusual due to their age, a testicular mass or hydrocele should be a suspect for possible metastatic disease.
