Birt–Hogg–Dubé Syndrome

Birt–Hogg–Dubé Syndrome is an autosomal dominant condition characterized by a triad of fibrofolliculomas, trichodiscomas, and acrochordons. Since the first description in 1977, many conditions have been described in association with its clinical triad. Recent epidemiological studies have shown a significant association between the occurrence of lesions in the fibrofolliculoma/trichodiscoma category with renal neoplasms and pneumothoracies. The BHD protein folliculin had recently been identified. The histological findings of the clinical lesions are distinctive. We report a patient with a history of melanoma who presented for routine surveillance. Facial lesions in the fibrofolliculoma/trichodiscoma category were identified. Diagnostic work‐up revealed concomitant multinodular goiter, pulmonary cyst, and renal mass. The patient later developed pneumothorax. Clinical manifestations, histological findings, associations, management, and a review of the Birt–Hogg–Dubé Syndrome are discussed.
