  Fig. 1. Dynamic contrast-enhanced CT findings of a gastric glomus tumor. (A) Arterial phase axial CT image showed a 2.4 cm, well-marginated mass (arrows) in the posterior wall of the gastric antrum. Note a peripheral globular and nodular enhancement of the lesion. Overlying gastric mucosa was intact suggesting that this was a subepithelial lesion. Note the thick intact overlying layer measuring 4.1 mm. (B) On portal venous phase CT, the mass (arrows) showed a central fill-in pattern of enhancement like in hepatic hemangioma. Note a very strong degree of enhancement of the lesion. In this patient, lesion-to-aorta enhancement ratio was 0.95. (C) On a 3D surface-rendered CT image, there was a well-demarcated subepithelial mass (arrows) in the posterior wall of the stomach.(D) Endoscopic ultrasonography using a 12 MHz transducer demonstrated a homogeneous echogenic mass (arrows) in the 4 th proper muscle layer (PM). Considering all imaging findings, the tentative radiologic diagnosis was a gastrointestinal stromal tumor.

  Fig. 2. Gastroscopic finding. Subsequent gastroscopy depicted an intraluminal protruding mass (*) with intact overlying mucosa, confirming this mass was a subepithelial tumor. Note a small ulceration (arrowhead) at the center of the mass.

  Fig. 3. Pathologic findings of resected specimen. (A) A photograph of gross specimen obtained after wedge resection demonstrated a 2.4 cm subepithelial tumor (arrows) located in the 4th proper muscle layer of the stomach (PM). (B) A microphotograph showed solid sheets of round, uniform glomus cells surrounding capillaries of varying shape (H&E, ×100). (C) Immunohistochemical staining for synaptophysin was strong positive for glomus tumor.
