title: Extensive psoriasis induced by pegylated interferon: a case report.
abstract: This paper describes the clinical course of a patient with chronic hepatitis C, genotype 2a/2c, previously treated with Interferon alpha2b and subsequently with Lymphoblastoid Interferon without any response, and also without any cutaneous side effects. The patient, a 50 year-old woman, was re-treated with Pegylated alpha2b Interferon plus Ribavirin for 24 weeks, at standard doses; during the third month of therapy she developed a mild form of psoriasis. However, encouraged by the progressive improvement of her transaminase levels and viral load decrease, the patient asked to continue the treatment; she normalized the transaminase levels during the fourth month and showed HCV-RNA negativity during the fifth month of therapy. Nevertheless, the psoriasis become worse, extending to over 75% of her body. Therapy was completed after sixth months. A month after the therapy was ceased, the patient's psoriasis receded spontaneously and completely. During the subsequent four years the patient did not experience any recurrence of either the hepatic disease or the psoriasis.
