Abstract
We experienced a rare case of juvenile submucosal heterotopia of gastric glands which was removed by endoscopic polypectomy with high frequency electric currents. The patient was 15-year-old female. X-ray and endoscopic examination revealed an elevated lesion which appeared a submucosal tumor on the posterior wall of the upper body of the stomach. Endoscopic ultrasonography findings suggested an epithelial tumor. Endoscopic polypectomy was performed. Microscopically, multiple heterotopic gastric glands were observed in the submucosal layer. The mucosal layer appeared partially injured, and the muscularis mucosa was obviously cleft. The heterotopic glands continu-ously shifted to the superficial normal glands through the cleft of muscularis mucosa. Ectopic glands were mostly composed of f oveolar epithelial cells, and a small amount of the fundic glands were also observed. From these findings, we concluded that this case is an acquired juvenile submucosal heterotopia of gastric glands arising from inflammation.
