Plasmapheresis, a treatment modality for necrobiotic xanthogranuloma.J Am Acad Dermatol. 1987 Aug; 17(2 Pt 2):351-4.JA
A case of necrobiotic xanthogranuloma treated with plasmapheresis is reported. This entity is characterized by multiple inflammatory, ulcerative nodules and atrophic plaques with a xanthomatous quality that develop in conjunction with a paraproteinemia. Successful healing of ulcerated lesions and lowering of the paraproteinemia was achieved by plasmapheresis in our patient with necrobiotic xanthogranuloma when cytotoxic therapy failed.
