A 69-years-old woman was admitted to the hospital because of a exogastric tumor 4 cm in diameter with a homogenous internal structure as demonstrated by abdominal CT. Endoscopic ultrasonography revealed a tumor described as a hypoechoic lesion containing a echo-free area with continuation to the 4th layer of the gastric wall. Endoscopic examination on admission showed extraluminal compression at the greater curvature of the upper body of the stomach, but at reexamination this finding was not recognized. Under a diagnosis of gastric leiomyoma showing exogastric pedunculated development, a wedge resection of the stomach including the tumor was performed laparoscopically. Histological diagnosis of the resected tumor was leiomyoblastoma. Gastric leiomyoblastoma showing exogastric pedunculated development is very rare, in refference to the literature. We report this case with some additional disccussion on the related literature.
