Abstract
Buschke-Ollendorff syndrome represents an autosomal dominant disorder characterized by connective tissue nevi and osteopoikilosis. Cutaneous lesions may contain either predominantly elastic fibers or predominantly collagen fibers or may show both connective tissue components. The disease results from mutations in LEMD3 (MAN1), which lead to enhanced transforming growth factor-β (TGF-β) signaling and resultant changes in fibroblast function. TGF-β alterations have been implicated in a number of fibrotic disorders, and it is therefore not surprising that a range of cutaneous and skeletal abnormalities have been associated with Buschke-Ollendorff syndrome. Herein, we report a novel association between ossifying fibroma and Buschke-Ollendorff syndrome and discuss how these conditions are likely to be mechanistically linked.
