Submucosal tumor of the stomach with bleeding ulcer was detected by upper endoscope and partial gastrectomy was performed. The tumor was 4.5 cm in the greatest diameter and had ulceration. Microscopic findings show atypical spindle cells that revealed CD34 (+), αSMA (+), s-100 (+) and c-kit (+) cell which led us to diagnose it as a gastrointestinal stromal tumor (GIST) -combined smooth muscle-neural type. Hematemesis or melena is rare symptom in patients with GIST (about 7%), and these tumors are considered to have high malignant potential. Therefore, we have to follow up the patient carefully.}, pages = {222--225}, title = {吐血を契機に発見された胃gastrointestinal stromal tumor (GIST)の1例}, volume = {73}, year = {2003} }
