Intraabdominal bronchogenic cyst.

INTRODUCTION: Bronchogenic cyst is pathology of the respiratory track. It consists of a defect during the embryological development of the tracheobronchial tree. Most common presentation is as a solid or cystic mass located in mediastinum, and it is usually diagnosed in relation to respiratory problems or recurrent infections in children. In adulthood, it is a rare pathology, and its diagnosis is usually incidental. CASE REPORT: We present a case of a patient with a paraesophageal cystic mass suggestive of intraabdominal esophageal duplication cyst but, after the histopathological examination, was discovered to be a bronchogenic cyst, something extremely rare as in most cases of subdiaphragmatic location; bronchogenic cysts appear as retroperitoneal lesions. DISCUSSION: After we review the current literature, surgical extirpation appears to be the treatment of choice due to potential complications, and laparoscopic approach is a feasibily and safe procedure for this pathology up to date.
