Cutaneous Bronchogenic Cyst of the Anterior Chest Wall

ABSTRACT

Cutaneous bronchogenic cyst is a benign congenital anomaly of the embryonic foregut and is an extremely rare lesion. This lesion is localized in the suprasternum, neck, mandible, and shoulders. The authors experienced this diseases in a 7-year-old male with a palpable mass on the anterior chest wall since birth. The mass was soft, non-tender, well demarcated and 5x4 cm in size. The histopathologic finding was a ciliated pseudostratified columnar respiratory epithelium at the cyst inner wall. The histopathologic diagnosis was a cutaneous bronchogenic cyst. The differential diagnosis includes branchial cleft cyst, thyroglossal duct cyst, teratoma, and cutaneous ciliated cyst. The purpose of this report is to document a cutaneous bronchogenic cyst, located on the anterior chest wall, an unusual localization of this lesion. Since this cyst has a potential for malignancy, treatment should consist of complete excision with follow-up.
