Abstract
It is very important to be aware of occurrence and distinctive histologic features of gastric glomus tumor because its clinical presentation and endoscopic ficdings are indistinguishable from other gastric tumors. A 58-year-old man was admitted because of intermittent epigastric pain and indigestion for 2 months. Physical examination and laboratory findings revealed within normal limits. Upper gastroendoscopy demonstrated a submucosal mass near the antrum with central mucosal depressionand peripheral multiple erosions. Endoscopic ultrasonography revealed a circumscribed mass that continued to the third and fourth layers which demonstrated a heterogeneous low echo pattern mixed with internal high echo spots. Histologically, the tumor cells have uniform small nuclei with inconspicuous nucleoli. Immunochemical analysis on the tumor cells expressed alpha 1 smooth muscle actin and the tumor cells are enveloped by reticulin fiber, individually or grouped. A case of glomus tumor of the stomach is herein reported with a review of literature. (Korean J Gastrointest Endosc 2000;21:559-562)
