Gastric glomus tumor.

Glomus tumors (GTs) are benign tumors originating from the glomus body which are usually solitary and small lesions. The vast majority are found in the distal extremities, particularly in the hand, wrist, foot and under the fingernails rarely involving visceral organs. Here we report a rare case of gastric GT presented to us with exsanguinating hematemesis and severe anemia. All the initial diagnostic tests were inconclusive. Contrast-enhanced computed tomography abdomen revealed a soft tissue density lesion within the first part of duodenum. Diagnostic laparotomy was planned and a mass of 3 × 2.5 × 2 cm was found at pylorus along greater curvature, without any evidence of lymphadenopathy or metastasis. Distal gastrectomy with gastrojejunostomy was done. Histopathology confirmed the diagnosis of a GT. Immunohistochemistry of tumor cells demonstrated smooth muscle actin and CD34 (very focal).
