Abstract
Cryoglobulinemic vasculitis is an immune-complex-mediated small-vessel vasculitis characterized by complement activation and endothelial injury. Its clinical manifestations are heterogeneous and may range from limited cutaneous involvement to systemic disease. We report the case of a 65-year-old woman who developed a symmetrical violaceous dermatosis involving the upper and lower extremities, accompanied by arthralgias and distal paresthesias. Laboratory investigations revealed marked hypocomplementemia and positive circulating cryoglobulins. Histopathological examination of a skin biopsy demonstrated leukocytoclastic vasculitis, leading to the diagnosis of idiopathic cryoglobulinemic vasculitis after exclusion of hepatitis C virus infection, autoimmune diseases, and associated hematologic malignancies, with no evidence of major systemic organ involvement. Treatment with corticosteroid- and cyclophosphamide-based immunosuppression achieved sustained disease control, resulting in approximately 90% symptomatic improvement. This case highlights the importance of recognizing cardinal manifestations, such as palpable purpura, arthralgias, and hypocomplementemia, when evaluating patients with suspected cryoglobulinemic vasculitis, even in the absence of identifiable secondary causes. Early recognition, histopathological confirmation, and a multidisciplinary approach are essential for establishing an accurate diagnosis and implementing timely therapeutic intervention aimed at preventing disease progression and irreversible organ damage.
