Abstract

|
|
|
Bronchogenic cyst is usually an extrapulmonary cyst formed as the result of an accessory lung bud from the foregut that becomes isolated from the rest of the tracheobronchial tree producing a usually solitary cyst. Most bronchogenic cysts are in the mediastinum with rare occurrence on the subcutaneous tissue over the sternum. We report a case of cutaneous bronchogenic cyst that occurred in the skin over the sternum in a 13-month-old boy. On ultrasonography, a well circumscribed non-echogenic cystic mass was observed measuring 1.5 1.3 cm. Histologically, the cyst was lined by cilicated, pseudostratified, columnar epithelium with interspersed goblet cells, and there were bundles of smooth muscle fibers, mucous glands, and lymphoid aggregates in the cyst wall.
