Multiple perifollicular fibromas: report of a case and analysis of the literature

The document described a case of a patient with multiple perifollicular fibromas and analyzed existing literature on the condition. Perifollicular fibroma was identified as a cutaneous hamartomatous proliferation involving the pilar connective tissue sheath, with a histological appearance of concentric collagen fibers around an unaltered hair follicle. Clinically, these fibromas were typically multiple and located on the face and upper trunk. The presentation was similar to Birt‐Hogg‐Dubé syndrome, which also included fibrofolliculomas, trichodiscomas, and acrochordons. The document suggested that earlier reports of multiple perifollicular fibromas might have been unrecognized cases of Birt‐Hogg‐Dubé syndrome.
