A Case of Gastric Glomus Tumor / 영남의대학술지

ABSTRACT

Gastric glomus tumor is a rare mesenchymal tumor that originates from modified smooth muscle cells of the glomus body. Glomus tumors are commonly observed in peripheral soft tissue, such as dermis or subungal region, but rarely in the gastrointestinal tract. A 39-year-old woman was admitted due to epigastric soreness. Upper gastrointestinal endoscopy revealed a subepithelial mass measuring 3.5cm with central ulceration at the lesser curvature-posterior wall of the antrum. Characteristically, contrast enhanced abdominal computed tomography scan demonstrated high enhancement of the submucosal mass up to the same level of the abdominal aorta in the arterial phase; this enhancement persisted to delayed phase. Due to the risk of bleeding and malignancy, wedge resection of the submucosal tumor was performed. Histologic findings were compatible with a glomus tumor.
