Pathologically confirmed pancreatic hamartoma after surgical resection with an aldosterone-producing adrenal tumor: a case report.

Pancreatic hamartoma is a benign tumor of the pancreas with an extremely low incidence and is commonly diagnosed by pathologic examination after surgery. This report describes the case of a 57-year-old female who was referred for the evaluation of a pancreatic mass and an adrenal incidentaloma. Further imaging studies suggested pancreatic neuroendocrine tumor and aldosterone-producing adrenal tumor. Pylorus-preserving pancreaticoduodenectomy was performed with the initial impression of a pancreatic neuroendocrine tumor. However, pathology results revealed a pancreatic hamartoma. Multiple endocrine neoplasia type 1 syndrome was discussed as a probable explanation for tumor masses in both the pancreas and adrenal gland.
