Hypergammaglobulinemic purpura of Waldenstrom associated with systemic lupus erythematosus: report of a case and review of the literature.

A patient with hyperglobulinemic purpura of Waldenstrom and systemic lupus erythematosus is reported. The coexistence of these two conditions which share a number of common clinical and laboratory features is rare. Treatment of the patient with prednisone, colchicine and hydroxychloroquine led to the improvement of the cutaneous vasculitis and a drop in ESR, serum gamma globulins and IgM and IgG rheumatoid factors. The features of nine other cases and the immunopathogenesis of the disease are reviewed.
