Clinical summary

Help

Imported from OMIM

Pityriasis rubra pilaris is an uncommon skin disorder characterized by the appearance of keratotic follicular papules, well-demarcated salmon-colored erythematous plaques covered with fine powdery scales interspersed with distinct islands of uninvolved skin, and palmoplantar keratoderma. Most cases are sporadic, although up to 6.5% of PRP-affected individuals report a positive family history. The rare familial cases show autosomal dominant inheritance with incomplete penetrance and variable expression: the disorder is usually present at birth or appears during the first years of life and is characterized by prominent follicular hyperkeratosis, diffuse palmoplantar keratoderma, and erythema, with only a modest response to treatment (summary by Fuchs-Telem et al., 2012).
