    Abstract:
    Bronchogenic cyst is a benign congenital developmental abnormality of the embryonic foregut. The most common extrapulmonary location of these lesions is the mediastinum. Over 50 cases of cutaneous bronchogenic cyst were reported in the English literature. Nevertheless, it is poorly recognized by clinicians and is sometimes confused with branchial cyst. In almost all cases the diagnosis is established by histopathologic examination. We report an unusual clinical presentation of bronchogenic cyst in a 4-year-old girl and review the literature. This lesion is four times more common in males than in females. The most common location is the suprasternal notch, followed by the presternal area, neck, and scapula. The characteristic histologic findings are a ciliated pseudostratified epithelial lining with the presence of smooth muscle cells, goblet cells and, less frequently, cartilage. Our review of the clinical and histologic features of all reported cases further delineates this entity and may facilitate its clinical diagnosis. Bronchogenic cyst should be included in the differential diagnosis of congenital cystic and nodular skin lesions on the upper chest, upper back, and neck.
