Abstract

Sub-Cutaneous Bronchogenic Cyst(SBC) is a rare entity and most likely represents ectopic or displaced mesenchyme during early development. We are reporting a 2-year-old girl with swelling over the sternum since birth and a discharging sinus. On evaluation, imaging revealed a well-defined cystic lesion in the pre-sternal deep subcutaneous region without intrathoracic extension. A complete excision was performed, and histopathological examination was suggestive of a bronchogenic cyst. The presentation of a subcutaneous bronchogenic cyst, a relatively rare entity, and its outcome, which was successfully treated with simple excision, are highlighted. This case is presented for its rarity and to create awareness about the entity.
