Abstract
Gastric glomus tumors are rare submucosal lesions that originate from the modified smooth muscle cells of the glomus body. They usually present as a submucosal tumor on endoscopy and a heterogeneous hypoechoic tumor in the third or fourth sonographic layer of the gastric wall on endoscopic ultrasonography. So they are often confused with other submucosal tumors such as gastrointestinal stromal tumor, schwannoma, and leiomyoma. Immunohistochemistry helps in differentiating glomus tumors from other submucosal tumors. The treatment of choice for these tumors is complete surgical resection. Most of the gastric glomus tumors are essentially benign in nature, so preoperative recognition of this lesion may spare the patient a more extensive resection. Herein, we present three cases of gastric submucosal tumor that were treated by a laparoscopic wedge resection and confirmed as glomus tumor on final pathology. (J Korean Surg Soc 2009;77:S9-12)
