Presternal bronchogenic cysts.
A presternal subcutaneous cyst was removed from a 21-month-old male infant. This is a rare congenital lesion that typically appears as a pinpoint opening over the sternum that periodically drains small amounts of mucinous material. Histologically, these lesions have the features of their intrathoracic and mediastinal counterparts. Surgical excision is advocated because of the potential for infection.
