Abstract

<p>The patient was a 50-year-old Japanese woman who was referred to our hospital for a positive fecal occult blood test. Colonoscopy showed a laterally spreading tumor (LST) in the cecum. Enhanced computed tomography (CT) showed a mass lesion with a maximum diameter of 54 mm on the ventral side of the ascending colon, and abdominal ultrasonography confirmed fluid inside, diagnosing a cystic tumor. Laparoscopic ileocecal resection was performed to resect both the cystic tumor and the cecal LST. Histologically, the cyst wall was covered with pseudostratified ciliated epithelium resting on a smooth muscle layer and mucous glands, leading to a diagnosis of a bronchogenic cyst. The postoperative course was uneventful, and the patient was doing well with no evidence of recurrence 9 months after surgery.</p><p>Since bronchogenic cysts in the abdominal region usually occur in the upper left abdomen, this case, which showed bronchogenic cysts in the lower right abdomen, is extremely rare. Thus, a rare case of an abdominal bronchogenic cyst is presented together with a review of the literature.</p>
