Macular skin lesions and extensive, heavy lymphoplasmacytoid cell infiltrates of the dermis were observed in a patient with primary IgM-kappa Waldenström's macroglobulinemia. Direct immunofluorescent microscopy on tissue sections disclosed that the lymphoplasmacytoid cells had a monoclonal IgM-kappa origin.
