Abstract
A 70-year-old woman was admitted to our hospital with complaints of bloody stool, diarrhea, and weight loss.Digital examination of the rectum, barium enema, endoscopy, and computed tomography revealed a huge rectaltumor with invasion to the uterus and vagina, and a pancreatic tumor and multiple liver tumors. Rectal amputationwith resection of neighboring organs, distal pancreatectomy with splenectomy, needle biopsy of one of the livertumors, and cannulation into the proper hepatic artery for postoperative chemotherapy were performed. Resectedtumors of the rectum, pancreas, and liver showed similar findings immunohistochemically and electronmicroscopically, and were diagnosed as rectal carcinoid tumor with metastasis to the liver and pancreas.
