Glomus tumors are benign lesions that originate from modified smooth muscle cells of the glomus body. These tumors are commonly observed in the dermis or subcutis, but they are only rarely found in the stomach. We describe here a 37-year- old male patient who presented with intermittent epigastric pain and in whom a submucosal tumor was encountered during performance of upper gastrointestinal endoscopy. A gastrofibroscopy demonstrated a 12 mm sized submucosal mass with central ulceration on the greater curvature-posterior wall of the high body. Endoscopic ultrasonography revealed a circumscribed inhomogeneneous hypo- echoic mass with a focal hyperechoic mass in the third layer of the stomach. We resected the entire mass using an endoscopic resection technique, and there were no complications. Histologically, the tumor cells had uniform small nucleuses with inconspicuous nucleoli. Immunochemical analysis of the tumor cells showed positivity for smooth muscle actin and negativity for CD34, KIT, S100 protein and desmin. This is the first case of a glomus tumor of the stomach that was resected by endoscopic resection.
