A Case of Epithelioid Type Gastric Gastrointestinal Stromal Tumor with Gastrointestinal Bleeding / 대한소화기내시경학회지

ABSTRACT

The stomach is the most frequently noted site (50~60%) of gastrointestinal stromal tumor. This tumor is categorized into three subtypes (the spindle cell type, the epithelioid type or mixed type) according to the shape of the cells that make up the tumor. We herein report on a case of gastrointestinal stromal tumor with an epithelioid subtype in a 60-year-old male. On admission, the patient presented with epigastric pain and melena. Endoscopy revealed a submucosal tumor with a central ulcer at the gastric body. Gastric wedge resection was performed. The tumor cells showed a rounded shape and positive staining for CD117. Because the epithelioid type gastrointestinal stromal tumor is unusual in Korea, we report here on this case along with a review of the relevant literature.
