[Malignant pancreatic oncocytoma].

A pancreatic oncocytoma in a 77 year old man is described. A CT scan showed liver metastases three years earlier. The patient died from complications after surgery for a perforated duodenal ulcer, and at autopsy a primary tumor in the tail of the pancreas and several liver metastases were found. The morphologic and biologic features of this unusual tumor are discussed.
