Cutaneous Waldenström's macroglobulinemia. A report of a case successfully treated with radiotherapy.

Waldenström's macroglobulinemia is a lymphoproliferative disorder that only rarely exhibits specific cutaneous findings. The authors present a case of Waldenström's macroglobulinemia in which the patient developed cutaneous lesions while his systemic disease seemed to be under control with chlorambucil therapy. A review of the scant literature regarding the response of cutaneous Waldenström's to treatment suggests that the skin lesions do not respond well to systemic therapy. This case was successfully treated with radiotherapy.
