Pityriasis rubra pilaris is a chronic scaly papular disease, of unknown etiology. Although there are familial cases, most of them are acquired. It Affects men and women equally, presenting bimodal incidence peaks in the first and fifth decades of life. We report a case of Pityriasis rubra pilaris in the classic adult form, on a male patient aged 40, who had chronic erythematous scaly follicular papules, 4 years of evolution, on the dorsum of the fingers. This study addresses the clinical course of the disease, differential diagnoses, histopathological findings and treatment with acitretin.
