case_images:  Endoscopy was attempted for the third time, which was unsuccessful at controlling the bleeding source ( Fig. 1 ).
case_images: Surgical exploration revealing a pedunculated fungating mass arising from the gastric fundus and body at the anterior surface. A: stomach; B: gastric mass (GIST).

case_images: A large pedunculated bleeding fungating gastric mass, originating from the anterior gastric wall, was found, measuring approximately 40 x 30 cm ( Figs. 2 and 3 ).
case_images: The resected mass, where A is the stomach, B is the fungating mass, and W is the gastric staple line from the wedge resection.

case_images: A large pedunculated bleeding fungating gastric mass, originating from the anterior gastric wall, was found, measuring approximately 40 x 30 cm ( Figs. 2 and 3 ). A wedge resection of the anterior gastric wall along with the mass ( Fig. 3 ) was performed, leaving behind healthy gastric margins.
case_images: Spindle cell tumor with blind-looking nuclei. There is no mild atypia with very rare mitotic figures.
  (d)
  An epithelioid component.
