A Case of Bronchogenic Cyst Presenting as a Submental Mass in the Adult / 대한이비인후과학회지

ABSTRACT

A bronchogenic cyst is an uncommon benign congenital anomaly of the primitive ventral foregut. Although bronchogenic cysts in the midline of anterior neck have been reported, they are known to occur very rarely. Moreover, it has never been reported to be located submentally in adults. Clinically, it is usually asymptomatic and thus incidentally diagnosed. Radiologically, it can not be differentiated from other cystic lesions. Therefore, it is pathologically confirmed only when there are bronchial tissues such as pseudostratified ciliated columnar epithelium, smooth muscle, mucous gland or cartilage. Since this cyst has potential for complication, a complete excision is mandatory. We recently experienced a case of bronchogenic cyst presenting as a submental mass in a 26 year-old man. In this article, we reviewed the etiology, the diagnosis, and the treatment of this case with a review of the literatures.
