A gastric carcinoid is a rare disease that accounts for only 0.3% of all primary gastric tumors. It can be multiple or occur with other types of tumor. However, there has been a recent increase in incidence. While carcinoids of the appendix and rectum are accompanied by adenoma or adenocarcinoma, a gastric carcinoid rarely occurs with an adenocarcinoma, particularly with a gastric adenoma. We encountered a case of a gastric adenoma and carcinoid mixed as a composite tumor, which became a lesion. The lesion resembled a type IIc early gastric cancer at the endoscopic examination and was removed by an endoscopic mucosal resection. We report a composite tumor of the gastric antrum composed of areas of adenoma and carcinoid, with an analysis of the histological components by immunohistochemical staining. Microscopically, the lesion was composed of a gastric adenoma and carcinoid as a composite tumor. (Korean J Gastrointest Endosc 2007;34:214⁣218)
