Figure

  • Fig. 1. (A) A 3-cm sized subepithelial tumor was noted at the fundus of the stomach. (B) Endoscopic ultrasonography showed a 2.4×2.3 cm round, hypoechoic mass in the proper muscle layer. (C) Endoscopic ultrasound-guided fine needle biopsy was performed.

  • Fig. 2. Pathologic findings of the biopsy specimens. (A) Histopathological examination reveals uniform spindle cells with high cellularity (hematoxylin and eosin ×200). (B) The tumor cells are strongly and diffusely positive for CD117 (×200).

  • Fig. 3. Macroscopic specimen from surgical resection.
