Abstract
It is very rare that ovarian carcinoma metastasizes to the pancreas, and pathological diagnosis is required to confirm the primary site. The present study reported a 73-year-old woman with serous carcinoma of the ovary that metastasized to the tail of the pancreas. Metastasis was confirmed by pathological and immunohistochemical examination of a biopsy of the ovarian tumor, an endoscopic ultrasound-guided fine-needle aspiration biopsy of the pancreatic tumor and computerized tomography-guided paraaortic lymph node biopsy. A biopsy of the ovarian tumor is useful to make a precise diagnosis and to determine proper treatment when ovarian and pancreatic tumors are identified at the same time and the primary neoplasm is uncertain.
