[Gastric intramucosal cancer spreading to submucosal heterotopic gastric glands].
A 73-year-old man was referred to our hospital for further examination of an intra-abdominal mass. An upper gastrointestinal endoscopy revealed a 0-IIa+IIc lesion on the lesser curvature of the middle body. The lesion was diagnosed as early gastric cancer (tub1, SM), and a partial gastrectomy was performed. Pathological evaluation revealed a well-differentiated intramucosal adenocarcinoma that had partially spread to the submucosa. On immunohistochemical examination, the lesion displayed an intestinal phenotype. The submucosal lesion had poor stromal reaction, and there was smooth muscle tissue surrounding the lesion. As mentioned earlier, we diagnosed the lesion as a gastric intramucosal cancer spreading to the submucosal heterotopic gastric glands.
