Necrobiotic xanthogranuloma is a rare, generalized dermatosis occurrin g in association with paraproteinaemia. We report on the clinical, his tological, immunohistochemical and electron microscopic findings in a 70-year-old woman affected by IgG gammopathy with lambda type immunogl obulins, hyperviscosity syndrome and necrobiotic xanthogranuloma. The rarity of the association of the systemic disorders reported, together with the noticeable extension of the skin lesions observed, are highl ighted.
