Pancreatic cancer metastasizing to the testis is extremely rare. We present the case of a 65-year-old man who complained of painless swelling of the left scrotum for 9 months. Scrotal ultrasonography revealed a mass in the left testis. Serum CA199 and CA242 were significantly elevated. F-FDG PET/CT was recommended for identifying potential malignancy and showed several hypermetabolic masses in the pancreas, left testis, and right lung. Resection of left testicular and pancreatic masses and fine-needle biopsy of right pulmonary mass were performed, and subsequent pathology confirmed pancreatic adenocarcinoma metastasizing to the testis and lung.
