Abstract
The patient, a 68‐year‐old woman with a long‐standing history of schizophrenia, was admitted to our hospital complaining of vomiting which had lasted approximately 3 weeks. Endoscopic examination of the stomach revealed a solitary pedunculated submucosal tumor, of approximately 2 cm in diameter, on the anterior wall of the upper body, close to the greater curvature. The lesion was endoscopically excised using a polypectomy snare without any complication. Microscopic examination was compatible with the diagnosis of gastric gland heterotopia showing submucosal proliferation of pseudopyloric glands, fundic glands and foveolar epithelium with fibromuscular stromal framework. The proliferating foveolar epithelium and fibromuscular stroma were in continuity with the overlaying gastric mucosa and muscularis mucosae, respectively. The lesion was entirely covered by normal gastric epithelium. No atypical cells were revealed in the lesion. The clinical significance of gastric gland heterotopia is unclear because of its controversial histogenesis and carcinogenetic potential. We herein report a rare case of solitary pedunculated gastric gland heterotopia with some review of scientific reports.
