CUTANEOUS LUNG-TISSUE HETEROTOPIA

Aims: We describe the clinical and pathological findings of a previous ly unreported cutaneous lung tissue heterotopia in a child. Case detai ls: The 3-year-old female patient developed a 8-mm secreting papule ov er her left scapula, Pathological examination revealed a lesion compos ed of bronchioles and alveoli within the subcutis and the dermis. with bronchiolar connection to the epidermis. Alveolar type II cells indic ating full pulmonary differentiation were detected with a monoclonal a ntibody (AMH 152). Conclusions: The described features suggest that th is lesion is a unique variant of rarely observed bronchus-like entitie s of the skin, designated as cutaneous bronchogenic cysts or cutaneous branchial cleft cysts.
