Necrobiotic xanthogranuloma with paraproteinaemia.

A 66-year-old man with necrobiotic xanthogranuloma associated with paraproteinaemia is described. He also had long-standing normolipaemic plane xanthomata. Treatment was with melphalan 0.15 mg/kg body weight/day. Initially, three 5-day courses were given at 4-weekly intervals but a fourth course was necessary after a further 4 months because of a deterioration in both his skin and associated systemic symptoms.
