Gastric glomus tumour: A case report

Abstract

Glomus tumours (GTs) are rare, mesenchymal neoplasms arising from the glomus body. Atypical sites, like the stomach, have been reported with extreme rarity since the usual location lies under the nail beds. We report a rare case of gastric GT in a 28-year-old female presenting with upper abdominal pain, intermittent haematemesis and melena. Contrast-enhanced computed tomography indicated a well-defined, heterogeneously enhancing lesion in the antral region of the stomach and a possibility of gastrointestinal (GI) stromal tumour (GIST). Upper GI endoscopy showed a wide-based lesion in the sub-mucosal plane with ulcerated mucosa. Laparoscopic excision of the tumour with primary closure of the defect was performed, with an uneventful post-operative course. Histopathological and immunohistochemical findings confirmed a gastric GT. Follow-up clinical and endoscopic examinations were normal. Gastric GTs should be a rare differential in patients with suspected GIST and upper GI bleed.
