Abstract
- Necrobiotic xanthogranuloma (NXG) is a rare, progressive, histiocytic disease characterized by destructive cutaneous lesions, a close association with paraproteinemia, multiple myeloma, hypertension, and multiple extracutaneous manifestations. Multiple indurated yellow-red plaques or nodules are commonly present in this disorder. The pathogenesis of NXG is poorly understood. Histopathologically, NXG features with hyaline necrosis or necrobiosis are present. We describe a patient with typical cutaneous and histologic findings of NXG with an associated monoclonal gammopathy.
