Multiple myeloma presenting as cryoglobulinemic vasculitis

Type I cryoglobulinemic vasculitis (CryoVas) is a rare entity occurring in the context of an existing lymphoproliferative disorder and often exhibiting severe cutaneous involvement.1 Cutaneous clinical manifestations include palpable purpura with necrosis and ulceration. Importantly, few reports of Type I CryoVas exist in the literature, and characteristic histopathologic features are not well-characterized. Herein, we present the clinical and histopathologic features of a case of recurrent Type I CryoVas in the setting of multiple myeloma.
