[A Case of Carcinoma of the Uterine Body, Right Ovary, and Duodenum in a Patient with Familial Adenomatous Polyposis].

We report a case of 4 carcinomas of the uterine body, right ovary, and duodenum in a patient with familial adenomatous polyposis (FAP). Her mother's family line carries FAP. She underwent proctocolectomy with ileoanal anastomosis for FAP when she was 20 years old. She was diagnosed with carcinoma of the uterine body and right ovary, and underwent abdominal total hysterectomy, bilateral salpingo-oophorectomy, and omentectomy at 48 years of age. The pathological examination revealed endometrioid adenocarcinoma of the uterine body (Stage ⅠB) and endometrioid adenocarcinoma of the right ovary (Stage ⅠA). Her diagnosis was Stage Ⅳ according to the Spigelman classification of duodenal polyposis, and she underwent pancreas-preserving total duodenectomy at 50 years of age. The pathological examination was conclusive for 2 carcinomas in the adenoma, which were 20 mm and 25 mm in diameter, respectively. She has been well without any evidence of cancer recurrence 20 months after the pancreas-preserving total duodenectomy.
