Abstract:
Bronchogenic cysts develop from tracheal diverticula or abnormal budding of the anterior foregut during embryological development. The most common extrapulmonary site of such cysts is the mediastinum; however, remote locations such as the lingual, intra-abdominal, and cutaneous regions have also been reported. Moreover, the postauricular location is an uncommon site for this entity. An 11-year-old boy visited our hospital with a long-standing mass in the postauricular area. Ultrasonography revealed a well-circumscribed anechoic nodule measuring 1.02×1.03 cm in size with posterior enhancement. The lesion was then completely excised. Pathological examination revealed a cystic lesion lined with ciliated pseudostratified columnar epithelium, consistent with a bronchogenic cyst. The patient had no local recurrence at 6th month follow-up. Herein, we report the first case of a bronchogenic cyst that developed in the postauricular area, and provide a review of the literature on cutaneous bronchogenic cysts.
