Adenosquamous pancreatic cancer producing parathyroid hormone-related protein.

An autopsy case of adenosquamous pancreatic cancer in a 61-year-old male patient with an elevated serum level of parathyroid hormone-related protein (PTH-rP) is reported. He was admitted to our hospital with a 1-month-long history of abdominal discomfort and progressive abdominal fullness. A computed tomography (CT) scan of the abdomen showed a retroperitoneal mass, approximately 10 cm in diameter, involving the pancreas, with round enhancement on contrast examination.
