A Case of Multiple Tumors Located in Structures Other than the Colon in a Patient with Familial Adenomatous Polyposis / 대한내과학회지

ABSTRACT

Most patients with familial adenomatous polyposis (FAP) undergo prophylactic colectomy. As a result, extracolonic manifestations including benign and malignant tumors are more common in patients with FAP, and duodenal cancer is now the main cause of death. However, duodenal adenomas and carcinomas are detected less frequently in Korea and Japan than in Western countries, and gastric cancer is more prevalent than in Western countries. In the present case, a 63-year-old man, who had undergone a total colectomy and an ileostomy 14 years previously, presented at our outpatient clinic complaining of discomfort at the ileostomy site. The patient had adenomas in the gallbladder and ileum, and adenocarcinomas in the duodenum and stomach. The interval between development of duodenal cancer and stomach cancer was only 4 months. Therefore, we suggest that more frequent endoscopic surveillance may be needed for these cases.
