抄録

A case of carcinoid tumor arising in the duodenal papilla was reported. A 42 year-old female was admitted with a complaint of nausea. Endoscopy of the upper gastrointestinal tract revealed a tumor in the second portion of the duodenum. The tumor with constriction at the base was three centimeters in diameter and had smooth mucosal surface. A shallow depression believed to be the papilla was identified at center of the tumor, but cannulation was not succeeded. Hypotonic duodenography revealed a tumor with diameter of three centimeters with bridging fold at the second portion of the duodenum. These findings suggested the diagnosis of carcinoid tumor, but the histopathological diagnosis was not obtained. At operation, the duodenum was incised first, and the tumor and the adjacent normal mucosa including the muscle of Oddi was resected. Frozen section examination suggested a neuroendocrine tumor with severe invasion to the muscle of Oddi. Pancreaticoduodenectomy was performed. The final histological diagnosis was carcinoid tumor, and no remnant of the tumor was found in the specimen resected by pancreaticoduodenectomy. Uncertainty of the preoperative diagnosis and the histological finding of the frozen section suggesting invasion to the muscle of Oddi required pancreaticoduodenectomy although there is possibility that unnecessary PD was performed in this particular case.
