Necrobiotic xanthogranulomatous reaction is a multiorgan, non-Langerhans cell histiocytosis with an unknown etiology. Occurrence in the salivary gland is extremely rare. We recently identified a case of necrobiotic xanthogranulomatous sialadenitis in a 73-year-old Korean woman who presented with a painless palpable lesion in the chin. There was no accompanying cutaneous lesion. Partial resection and subsequent wide excision with neck dissection were performed. Pathological examination showed a severe inflammatory lesion that included foamy macrophages centrally admixed with neutrophils, eosinophils, lymphocytes, plasma cells, and scattered giant cells, as well as necrobiosis. During the 12-month postoperative period, no grossly remarkable change in size was noted. Necrobiotic xanthogranulomatous inflammation may be preceded by or combined with hematologic malignancy. Although rare, clinicians and radiologists should be aware that an adhesive necrobiotic xanthogranuloma in the salivary gland may present with a mass-like lesion. Further evaluation for hematologic disease and close follow-up are needed when a pathologic diagnosis is made.

Necrobiotic xanthogranuloma(NXG) is a characteristic cutaneous manifestation associated with paraproteinemia. A case of NXG associated with an IgG (lambda) monoclonal gammopathy occurred in a 48-year-old man. Skin lesions were dome-shaped, hard palpable nodules, 2x3 cm to 4x4 cm sized, on both arms and forearms. They were arranged in a linear pattern. Also, hard palpable tumors, 1x2 cm to 2x3 cm in size, were present on the left leg and the dorsum of the left foot. They were violaceous, slightly protruded, and hard on palpation. Histologically, the lesion was characterized by inflammatory xanthogranuloma with broad hands of hyaline necrobiosis. Many foreign body type of bizarre giant cells, Touton type of giant cells and foamy histiocytes were infiltrated into the dermis and subcutaneous fat tissue. Three days after medication with ledercort and immuran, the cutaneous masses decreased in size and became soft.
