Etanercept-induced clinical remission of type II pityriasis rubra pilaris with rheumatoid arthritis.

Pityriasis rubra pilaris (PRP) is a rare papulosquamous dermatosis characterized by keratotic follicular papules, erythematous scaling, pahnoplantar keratoderma and a variable degree of erythroderma. Type I PRP, the most common adult form, has a typical clinical manifestation, and remission in these patients can be achieved within 3 years. However, the rare type II PRP presents atypical features and has a long disease duration. We describe here a case of type II PRP associated with rheumatoid arthritis (RA) that achieved clinical remission with etanercept therapy.
