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 (AU)
