Abstract

Gastrointestinal stromal tumors (GISTs) are uncommon tumors that originate from primitive mesenchymal cells. Because GISTs develop throughout the gastrointestinal tract, they present variable heterogenous clinical manifestations such as gastrointestinal bleeding. We report a case of massive gastrointestinal bleeding from jejunal stromal tumor mimicking arteriovenous malformation. (Korean J Gastrointest Endosc 2003;26:214⁣219)
