Cryoglobulinemia vasculitis associated with adult-onset Still's disease.

KEY CLINICAL MESSAGE: The present case indicates that cryoglobulinemia vasculitis should be considered in the differential diagnosis of purpura in patients with adult-onset Still's disease (AOSD).

ABSTRACT: The presence of purpura is suggested in adult-onset Still's disease (AOSD) hematological complications of hemophagocytic syndrome, disseminated intravascular coagulation, or thrombotic microangiopathy. We herein report a case of AOSD complicated by cryoglobulinemia vasculitis presenting with purpura.
