Abstract
We present a 41-year-old female who was admitted to our hospital with a history of 2-month epigastric pain and vomiting. Physical examination was normal. Upper gastrointestinal endoscopy showed a sessile submucosal tumor with central ulceration in the gastric body-antrum. Biopsies revealed a gastric mucosa without changes. Nevertheless, endoscopic ultrasound-guided biopsies showed interlacing bundles of spindle cells. The immunohistochemical study was negative for CD117 and smooth muscle actin and positive for S100 protein. A CT scan identified a heterogeneous mass in the stomach wall.
