✦ Synopsis

Gastric neoplasms can be imaged by sonography when they cause wall thickening, intraluminal mass lesions, or gastric dilatation secondary to obstruction.' We present a rare case of a glomus tumor of the stomach which was incidentally detected on barium upper gastrointestinal examination and which sonography delineated as a mural soft tissue mass.

CASE REPORT

A 40-year-old white man with a 14-month history of ulcerative colitis was admitted to the hospital because of actute exacerbation of his symptoms. A barium upper gastrointestinal examination demonstrated a small filling defect on the greater curvature of the antrum of the stomach (Figure 1 , left).

Differentiation between a mural and extramural lesion could not be made. Sonography showed a rather homogeneous, hypoechoic, 2.5 cm in diameter, submucosal, solid mass protruding into the lumen of the antrum. Its border was smooth, but no capsule was identified (Figure 1, right). Scanning after water ingestion confirmed the mural origin of the lesion, which was separate from the pancreas. The rest of the upper abdomen was normal. It was felt this was a submucosal leiomyoma. The patient subsequently had protocolectomy due to refractory ulcerative colitis, at which time a 2.5-cm fleshy mass was resected from the gastric antrum.

Histologically, the tumor consisted of small, uniform, round cells with hyperchromatic nuclei From the
