- Abstract
- Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract, and cystic changes are commonly observed. However, there have been few reports of cases of exophytic pedunculated GIST with cystic changes. Here, we report a 45-year-old man who presented with a palpable mass in the left upper quadrant of the abdomen. The mucosal folds were endoscopically abnormal, but there was no mucosal lesion. Computed tomography demonstrated a large, low-density cystic lesion surrounding an enhanced nodule in the greater curvature of the gastric body, and there was no tumor infiltration to other organs. The patient underwent hemigastrectomy and the lesion was shown to be an exophytic pedunculated cystic tumor. Histopathological examination showed epithelioid cells with marked hemorrhaging. Immunohistochemical examination indicated that most of the tumor cell cytoplasm was positive for the c-kit protein (CD117) and CD34. The tumor was diagnosed as an exophytic pedunculated GIST of the stomach with cystic changes. (Korean J Med 78:222-225, 2010)
