Glomus tumor in the stomach: Computed tomography and endoscopic ultrasound findings

Figure 1 A 57-year-old man presented with intermittent dull abdominal pain after a duration of 1 year with a glomus tumor in the lesser curvature. A: A plain computed tomography (CT) scan of the tumor revealing a clear regular contour and an isodensity mass; B: The mass shows dense homogeneous enhancement with an intact overlying mucosa on early-phase contrast-enhanced CT; C: The mass shows continuous homogeneous enhancement on delay-phase contrast-enhanced CT.

Figure 2 Gastroscopy shows a submucosa eminent lesion in the stomach wall. A: Endoscopic ultrasonic shows a solid mass originating from the superficial layer of the muscular propria. It is 20 mm × 16 mm in size, and a marginal halo can be observed; B: The mass appears as a round, hypoechoic lesion with homogenous echogenicity. After a failed endoscopic submucosal dissection with ligation for the treatment of the small tumor, a subtotal gastrectomy was performed; C: Microscopic examination shows numerous dilated, thin-walled vascular spaces surrounded by uniform glomus cells (hematoxylin and eosin stain, × 50).
