Abstract
Although duodenal neoplasms are rarely encountered, we experienced a case of giant duodenal leiomyoma. A 71-year-old female was admitted to the gynecologic ward under the diagnosis of an ovarian tumor. She had complained of a huge abdominal mass and chronic anemia of more than 2 years' duration. She was operated on two days after hospitalization, at which time a large tumor involving the duodenum, pancreas head and the transverse mesocolon was found. Both ovaries were intact. We then performed a pancreaticoduodenectomy with right hemicolectomy. This tumor aorse from the second portion of the duodenum, compressing the pancreas head and bile tract and firmly adhering to the transverse mesocolon. Microscopically it consisted of interlacing sheets of smooth muscle cells without mitotic figures or cellular atypias. The postoperative course was uneventful and the patient is now pursuing her regular activities without any trouble.
