A 49-year-old woman presented with epigastric discomfort and vomiting of several months' duration.
Examination and standard laboratory tests results were normal. At EGD, a 15-mm ulcerated, protruding lesion with the appearance of a submucosal tumor was present in the prepyloric antrum. EUS revealed a hypoechoic, nodular, and poorly demarcated lesion with a heterogeneous internal echo pattern and a linear, highly echogenic structure situated in the muscularis propria. A GI stromal tumor was suspected, and the lesion was resected laparoscopically.
The resection specimen consisted of a 13-mm, nodular, ulcerated, submucosal lesion with an internal cavity that contained dense pus and a foreign body that proved to be a fish bone.
