[Early stomach cancer derived from heterotopic glands--a case report].

A 69-year-old man with early gastric cancer derived from heterotopic glands in the submucosal layer is reported. Macroscopically, two flat elevated lesions were found on the anterior and posterior walls of the stomach; histologic examination revealed submucosal cystic glands in each lesion. Carcinoma was proved only in the deeper part of the submucosal glands on the anterior wall; no obvious cancerous change was confirmed in the overlying mucosa and heterotopic glands in the posterior wall.
