Summary

Excerpted from the GeneReview: Birt-Hogg-Dubé Syndrome
The clinical characteristics of Birt-Hogg-Dubé syndrome (BHDS) include cutaneous manifestations (fibrofolliculomas, acrochordons, angiofibromas, oral papules, cutaneous collagenomas, and epidermal cysts), pulmonary cysts / history of pneumothorax, renal cysts, and various types of renal tumors. Disease severity can vary significantly even within the same family. Skin lesions typically appear between the second and fourth decades of life and typically increase in size and number with age. Lung cysts are mainly in the basal lung regions; most individuals are asymptomatic but at high risk for spontaneous pneumothorax. Renal tumors can be bilateral and multifocal. The most common renal tumors are a hybrid of oncocytoma and chromophobe histologic cell types (oncocytic hybrid tumor); clear cell carcinoma and oncocytoma are also common.
