[Are multiple trichodiscomas/fibrofolliculomas the Birt-Hogg-Dubé syndrome?].

Birt-Hogg-Dubé syndrome is a rare autosomal dominant disease caused by a mutation in the FLCN gene and presents with a triad of multiple fibrofolliculomas, trichodiscomas, and masses that clinically resemble fibroepithelial polyps (acrochordones), accompanied by an increased risk of kidney tumors and lung cysts. The paper provides a literature review supplemented by clinical cases and the morphological pattern of skin lesions. It presents the clinical and morphological features of cutaneous manifestations of the syndrome and gives diagnostic criteria.
