Bronchogenic cysts are congenital cystic lesions caused by abnormal budding of the primitive tracheobronchial tube. Most bronchogenic cysts are found in the mediastinum, whereas abdominal bronchogenic cysts are rare with only 39 cases reported in the literature to date. The indication of surgical intervention is still controversial in previous studies. In the present study, we report a case of a bronchogenic cyst of the stomach in an adult who was treated by wedge excision.
