Bronchogenic cyst presenting as a supraclavicular mass.

Bronchogenic cyst is one of the more common congenital pulmonary anomalies. It is related to abnormal budding of the tracheobronchial tree during embryologic development. These lesions may present as a mass in the lung parenchyma in the mediastinum or within or below the diaphragm. An unusual case of bronchogenic cyst presenting as a mass in the supraclavicular fossa of a 24-year-old woman is reported. Treatment of bronchogenic cyst consists of excision of the mass. Recurrence is rare if excision is complete.
