A case of cutaneous bronchogenic cyst presenting with lymphoid follicles.

Cutaneous bronchogenic cysts are rare, and stem from developmental abnormalities of the tracheobronchial tree. The condition is often misdiagnosed clinically, with the correct diagnosis usually established by histopathologic examination. Published reports of bronchogenic or branchial anomalies are increasing, and the traditional defining characteristics of location and histopathology are proving to be less reliable for the identification of cutaneous bronchogenic cysts. In this report, we describe a case of a cutaneous bronchogenic cyst that presented with unusual histologic features, and was associated with several lymphoid follicles.
