A Case of Gastric Cavernous Hemangioma Diagnosed by Endoscopic Submucosal Dissection

Abstract

Gastric cavernous hemangioma is a relatively rare benign gastric disease. Gastric hemangiomas are most commonly encountered in adulthood, although they can occur in any age group. While surgical resection is the curative treatment, endoscopic resection can be performed for treatment of selected cases. The patient was a 53-year-old male who was referred for evaluation of incidentally detected gastric subepithelial tumor with dense vascularity and oozing on the apex of the lesion. An EUS revealed a homogenously hypoechoic mass confined to the submucosal layer that showed no continuity with adjacent vessels, and there was no regional lymphadenopathy. Endoscopic submucosal dissection was successfully performed with en bloc resection. The final diagnosis was benign cavernous hemangioma of the stomach.
