BACKGROUND Infection by the hepatitis C virus(HCV) is currently considered to be a global health issue, with a high worldwide prevalence and causing chronic disease in afflicted individuals. The disease largely involves the liver but it can affect other organs, including the skin. While leukocytoclastic vasculitis has been reported as one of the dermatologic manifestations of HCV infection, there are no reports of this condition as the first symptom of HCV recurrence after liver *** SUMMARY We report here a case of leukocytoclastic vasculitis in a liver transplant recipient on maintenance immunosuppression. The condition presented as a palpable purpura in both lower extremities. Blood and urine cultures were negative and all biochemical tests were normal, excepting evidence of anemia and hypocomplementemia. Imaging examination by computed tomography showed a small volume of ascites, diffuse thickening of bowel walls, and a small bilateral pleural effusion. Skin biopsy showed leukocytoclasia and fibrinoid *** biopsy was suggestive of HCV recurrence in the graft, and HCV polymerase chain reaction yielded 11460 copies/mL and identified the genotype as 1 A. Treatment of the virus with a 12-wk direct-acting antiviral regimen of ribavirin, sofosbuvir and daclatasvir led to regression of the symptoms within the first 10 d and subsequent complete resolution of the *** This case highlights the difficulties of diagnosing skin lesions caused by HCVinfection in immunosuppressed patients.
