From OMIMDystrophic epidermolysis bullosa is an inherited skin fragility disorder associated with anchoring fibril abnormalities and sublamina densa blistering.
EB pruriginosa is a rare distinct clinical subtype of dystrophic EB in which skin fragility, blistering, and scar formation are associated with intense pruritus, nodular prurigo-like lichenified lesions, nail dystrophy, and variable presence of albopapuloid lesions (McGrath et al., 1994; Cambiaghi et al., 1997). The onset of these clinical features may be evident in early childhood, but in some cases is delayed until the second or third decade of life. Autosomal dominant, autosomal recessive, and sporadic inheritance patterns have all been described in this disorder.
