A 53-years-old man presented with RUQ pain for 2 years. The CT abdomen showed two homogeneous enhancing submucosal nodules at gastric body, 1.6 cm and 1.9 cm in size at lesser and greater curvatures of stomach. The upper GI endoscope revealed two submucosal nodules at lesser and greater curvatures of gastric body without any ulcer. He was undergone explor-laparotomy and wedge resection of both lesions were performed. Pathologic examination reported gastrointestinal stromal tumor (GIST) with coexisting gastric leiomyoma. To our best knowledge, this is the first case of coexisting gastric GIST and leiomyoma.
