Simultaneous appearance of early gastric cancer and GIST

Abstract

We present the case of a 74-year-old male patient who was admitted with symptoms of upper digestive bleeding. Endoscopy of his upper digestive tract found an ulcerated lesion and a subepithelial lesion in his stomach. Complete studies including gastric endoscopic ultrasound showed a mucosal lesion infiltrating the submucosa which was suggestive of early gastric cancer as well as a subepithelial lesion on the muscle that was suggestive of a gastrointestinal stromal tumor (GIST). Staging showed no metastatic compromise, so surgery was performed, and histology subsequently confirmed the findings.
