Abstract
Anaplastic pancreatic carcinoma is rare and is associated with poor prognosis. We encountered an extremely rare case of triple cancer that included anaplastic pancreatic carcinoma. A 71-year-old man was identified as having multiple liver tumors and a tumor near the pancreas head. After careful examination, he was diagnosed with a 2-cm cystic tumor on the dorsal side of the pancreas head, multiple hepatic hemangiomas, left ureter cancer, and right lung cancer. The patient first underwent an operation at the Department of Urology. However, he was referred to our department 1 month later because of obstructive jaundice caused by the rapidly growing pancreatic tumor. Given the sudden change, we strongly suspected that the tumor was malignant and performed a subtotal stomach-preserving pancreaticoduodenectomy. The solid tumor exhibited expansive growth, necrosis, and bleeding at the uncinate process of the pancreas. On postoperative pathological examination, the tumor was identified as a pleomorphic type anaplastic pancreatic carcinoma. We detected multiple liver metastases 2 months after the surgery and performed systemic chemotherapy, but the patient died 1 year 3 months after the surgery.
