Sofosbuvir induced leucocytoclasic vasculitis: a case report.

Background: We describe a case of leucocytoclasic vasculitis induced by Sofosbuvir and its disappearence after the end of the therapy. The hepatitis C virus, firstly described in 1989, is a major global health problem, with high morbidity and mortality. We observed a temporal relationship between the treatment and the onset of vasculitis. We emphasize the multidisciplinary approach to the patients with liver disease to improve the quality of life of these patients.

Case presentation: A 53-year-old Caucasian man with a history of hepatitis C virus genotype 1 infection was examined at our Department of Dermatology for the occurrence of palpable purpura. The patient referred that the first appearance of the dermatoses was about one month after initiation of therapy with Sofosbuvir for hepatitis C.

Conclusions: Vasculitis appeared after the beginning of Sofosbuvir and, even though it was treated with different medications proved to be effective, it disappeared only after the conclusion of the therapy, giving a strong evidence to be a drug eruption.
