Abstract
We report a case of pancreatic pleomorphic carcinoma. A 71-year-old man with obstructive jaundice and liver dysfunction was admitted to our hospital. Computed tomography showed a low density tumor measuring 30mm in diameter at the uncus of the pancreas. Magnetic resonance imaging revealed stenosis in the lower bile duct. Pylorus preserving pancreaticoduodenectomy, and partial resection of the liver were performed. The resected specimen was a soft tumor with partial necrosis; the cut-surface was yellowish white. The tumor showed expansive growth comprising various amounts of solid proliferated pleomorphic mononucleated or multinucleated malignant cells. The diagnosis was pleomorphic carcinoma of the pancreas. The postoperative course was good, but the patient died from liver failure one month after the operation.
