Physical examination showed more than 20 scattered, irregularly shaped, well-demarcated, yellowish red nodules and plaques measuring 0.5 - 15 cm in diameter on the trunk. The plaques on the right lower abdomen showed central ulceration and atrophy with scar formation. Plasma protein electrophoresis revealed that the levels of immnnoglobulin G （IgG） and kappa light chain were 18.3 g/L and 20.70 g/L respectively. Histopathologically, large necrobiotic areas and granuloma were observed alternately in the dermis and subcutis. There were numerous Touton giant cells, foreign body giant cells and fomny histioeytes in the granuloma, and many cholesterol clefts were found in the center of necrobiotie areas with the formation of lymphoid follicles in some regions. Both eyes of the patient were involved to different degrees. He was diagnosed as necrobiotie xanthogranuloma with IgG kappa paraproteinemia and eye involvement.
