A 75-year-old man with dysphagia was found in an upper gastrointestinal series to have a tumor shadow at the fornix. A diverticulum was seen on the anterior subphrenic esophageal wall. An elevated lesion was seen from the lower proximal esophagus in endoscopy. The preoperative diagnosis was a gastric leiomyoma and subphrenic esophageal diverticulum. The diverticulum was seen on the proximal side of the tumor which located at the abdominal esophagus. The tumor was enucleated, the diverticulum was made contrary inside and the opened muscular layer was sutured. Histopathological diagnosis of the resected tumor was esophageal leiomyoma. In the many previous reports of our country, the origin of the esophageal diverticulum associated with esophageal leiomyoma was traction. In our case, it is suggested that the diverticulum developed as a result of both traction and pulsion of the esophageal wall related to the growth of the tumor.

Key words
