[Bronchogenic cyst of the tongue].

OBJECTIVES Bronchogemc cyst is a rare aberration secondary to abnormal detachment of accessory lung buds from the primitive foregut. Through one case of bronchogenic cyst of the tongue, the authors made a review of this exceptional localisation. MATERIAL AND METHODS We report one case of bronchogenic cyst of the tongue treated in the Ibn Sina Hospital. RESULTS Our patient was a new born admitted in our formation for a voluminous cystic mass ot the tongue, responsible of difficulty for mouth occlusion and feeding The radiology I confirms the liquid nature of this mass. The treatment was surgical, and the diagnosis of bronchogenic cyst was histological. CONCLUSION Bronchogenic cysts are generally intrathoracic. The localization in the cervico-facial area is rare, and only 4 cases of bronchogenic cyst of the tongue were described in the literature. The clinical presentation is non specific, depending on the volume of the cyst. Radiology permits to confirm the nature of the mass. The certitude diagnosis is histological: bronchogenic cysts are lined by pseudostratified ciliated columnar epithelium with accessory tissues in the cyst wall, smooth muscle, seromucinous glands and cartilage, simulating a bronchus. Complete surgical excision is the base of the treatment.
