Mixed cryoglobulinemia; a rare presentation of Waldenström macroglobulinemia

Abstract

Type II mixed cryoglobulinemia is a systemic disease mediated by immune complexes. Renal involvement is present in almost one third of the cases and the membranoprolifer-ative pattern is the most common histological presentation. In turn, in Waldenström macroglobulinemia, renal impairment is rare, with few cases of associated cryoglobu-linemia being reported. The authors present the case of a patient with type II mixed cry-oglobulinemia associated with Waldenström macroglobulinemia diagnosis.
