The histopathologic features in four cases of subcutaneous xanthogranuloma were reviewed. All patients were elderly men and no associated diseases or hyperlipidemia were present. The microscopic picture was uniform in seven biopsy specimens: foam cells and masses circumscribed by Touton cells replacing the adipose tissue. Most cells, including foam cells, showed a positive reaction for the macrophage marker MAC387. Diffuse, sparse T cells and focal perivascular B cell nodules were identified. Electron microscopic examination showed histiocytes and lysosome-rich cells with myelin bodies. All patients are alive and well. We believe that we have identified a form of adult subcutaneous xanthogranuloma syndrome that can be initially confusing and lead to overdiagnosis and overtreatment.

Necrobiotic xanthogranuloma is a newly recognized cutaneous manifestation associated with paraproteinemia. Necrobiotic xanthogranuloma is distinctive clinically by yellowish-red nodular lesions, often ulcerated, with predilection for the periorbital area and ocular involvement. Histologically, it is characterized by the combination of inflammatory xanthogranulomas together with areas of necrobiosis. These skin lesions are associated with a dysglobulinemia and preceded the development of an IgG lambda myeloma in a previous patient. Hyperlipidemia may be found in some patients. A case of necrobiotic xanthogranuloma is reported, occurring in a 46-year-old man and associated with an IgG kappa myeloma.

Necrobiotic xanthogranuloma with paraproteinemia is characterized by multiple nodules or plaques that involve the periorbital area along with other parts of the body. A dysproteinemia due to an IgG paraprotein is associated with the condition; low serum complement, cryoglobulinemia, leukopenia, and hyperlipemia are also sometimes seen. Multiple myeloma is present in some cases. Two cases of necrobiotic xanthogranuloma with IgG monoclonal gammopathy were seen. Both initially had ocular symptoms and in the second case, the ocular manifestations have dominated the clinical picture. Histologically, these granulomas are characterized by collagen necrobiosis and by the presence of many foamy histiocytes and Touton giant cells. Because necrobiotic xanthogranuloma with monoclonal gammopathy frequently has prominent manifestations in the orbital region, may result in dysfunction of the eyelids or extraocular muscles, and is associated with potentially life-threatening systemic conditions, its recognition by the ophthalmologist is important.

Eight patients had multiple xanthomatous plaques and subcutaneous nodules that had a predilection for the periorbital area, flexures, and trunk and that tended to ulcerate. Skin biopsy specimens showed a combination of xanthogranulomatous nodules with necrobiosis. All patients had an accompanying dysproteinemia, which was a monoclonal IgG paraprotein in six. Hyperlipidemia, low serum complement, and cryoglobulinemia were variable features. Five patients had leukopenia. Bone marrow examination showed myeloma in two patients, a lymphoproliferative process in one, and some atypical plasma cells in two. Cutaneous necrobiotic xanthogranuloma is a distinctive histologic pattern most frequently related to plasma cell dyscrasias, and it should be distinguished from normolipemic plane xanthoma and other necrobiotic granulomas.

A 50-year-old woman presented to our clinic for evaluation of numerous recurrent, pruritic papules on her upper extremities. She reported a 2- to 3-year history of up to eight unique lesions on the bilateral upper arms that would initially appear as firm papules before gradually softening and flattening out, leaving residual pink macules (Figure 1A). Her medical history was notable for mild hyperlipidemia. On presentation, she had several erythematous papules with overlying telangiectasias scattered throughout her bilateral upper arms. One lesion of concern over the left deltoid had been present for 5 months without signs of regression (Figure 1B). Pathology of this and a similar lesion showed histiocytes forming Touton giant cells with foamy cytoplasm consistent with a xanthogranuloma (AXG). Results from immunoperoxidase stains were negative for factor XIIIa and CD1a, diffusely positive for CD68, and focally positive for S100 (Figure 2).

Yellowish papules, nodules, or plaques, namely "xanthomatous" lesions, may be seen on the eyelids in the course of various disorders. The prototype is "xanthelasma palpebrarum" (XP) that is localized only to the eyelids and may be associated with hyperlipidemia. On the other hand, different types of normolipemic disorders may also cause xanthomatous eyelid lesions. Among these, Langerhans cell histiocytosis, diffuse normolipemic xanthoma, and non-Langerhans cell histiocytoses (papular xanthoma, juvenile xanthogranuloma, xanthoma disseminatum, adult-onset xanthogranuloma, adult-onset asthma and periocular xanthogranuloma, necrobiotic xanthogranuloma, Erdheim-Chester disease, Rosai-Dorfman disease, and reticulohistiocytosis) can be listed. The eyelid findings of this heterogeneous group of disorders are challenging to differentiate from each other due to common clinical aspects that may even sometimes mimic XP. Nodularity, induration, ulceration, diffuse eyelid involvement, and extension from eyelids to the neighboring skin may represent the clinical features of xanthomatous lesions other than XP. It is necessary to obtain a thorough history and exclude XP and then perform detailed dermatological and systemic examination, biopsy for histopathologic confirmation, and appropriate specific imaging screens. As some of the conditions may be associated with other systemic disorders, especially malignancies, the differentiation of xanthomatous eyelid lesions has a critical importance, and clinical signs can be guiding.
