Gastric glomus tumor: a hypervascular submucosal tumor on power Doppler endosonography.

Gastric glomus tumors are rare submucosal lesions that typically occur in the fourth endosonographic layer. We describe a 69-year-old patient who presented with intermittent epigastric pain and in whom a submucosal tumor was encountered during upper gastrointestinal endoscopy. Endosonography revealed a heterogeneous, hypoechoic fourth-layer tumor. Power Doppler imaging revealed prominent intratumoral vascular signals demonstrating its hypervascular nature. A diagnosis of glomus tumor was made via histopathologic evaluation of the resected tumor. Copyright 2007 Wiley Periodicals, Inc.
