His family history was negative for renal neoplasms, pneumothorax, and seizures, and his spirometry results were normal. CT showed multiple peripheral, lentiform, perifissural, and intraparenchymal thin-walled cysts in both lungs (Figure, C). Skin biopsy of the facial papules showed fibrofolliculomas (Figure, B), which is a major diagnostic criterion for Birt-Hogg-Dubé syndrome. Notably, one major criterion or two minor criteria are needed to confirm diagnosis (1). Abdominal imaging showed no renal mass.Images in 47-year-old man with 30-pack-year smoking history who presented with chronic nonproductive cough. (A) Photograph of patient’s face shows multiple dome-shaped, smooth, whitish facial papules (arrows). (B) Photomicrograph (hematoxylin-eosin stain; original magnification, ×40) of excisional biopsy of papule shows typical findings for fibrofolliculoma. These are characterized by proliferation of follicular epithelium with prominent epithelial strands, with whirling architecture (open arrow), surrounded by perifollicular fibrous sheath (solid arrow). (C) Thin-section axial chest CT scan shows multiple thin-walled peripheral lentiform cysts (arrows) in both lungs characteristic of Birt-Hogg-Dubé syndrome.Download as PowerPointOpen in Image Viewer Birt-Hogg-Dubé syndrome is an autosomal dominant, multisystem disorder caused by a mutation in the folliculin gene, FLCN (17p11.2). This inherited disease is characterized by cutaneous lesions, renal tumors, cystic lung disease, and spontaneous pneumothorax (1). Skin lesions include fibrofolliculomas, trichodiscomas, and acrochordons (2). MRI of the kidneys is recommended every 3 years to exclude the known propensity for the development of chromophobe cell cancer and oncocytomas in these patients. Pleurodesis is frequently performed after the initial episode of spontaneous pneumothorax because of a high incidence of recurrence (3).Disclosures of Conflicts of Interest: S.G.
