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.

Necrobiosis Lipoidica is a skin disorder of unknown cause, which shows characteristic clinical and histological findings. With histochemical studies, we report of a case which oecurred on the both pretibial surfaces in a 5]-year-old female. Having had treatment with aspirin and dipyridarnole for 9 months. The results were successful.

Necrobiotic xanthogranuloma (NXG) is a rare multisystemic disease that manifests as cutaneous inflammatory lesions and has a strong association with paraproteinemia and an increased risk of plasma cell dyscrasias and other lymphoproliferative disorders. Its general skin manifestation is multiple, asymptomatic, indurated nodules or plaques with a yellowish hue which frequently affect the periorbital regions. This case is unusual in that cutaneous lesions developed only at the extremities without periorbital involvement, accompanied by multiple myeloma.

A 31-year-old male patient had malignant atrophic papulosis that afected the skin only. He had multiple typical porcelain-white skin lesion on the face and trunk without abdominal symptoms. Histopathologic studies showed moderate inflammatory infiltration in addition to the typical cone-shaped region of necrobiosis, There are no satisfactory treatment modes, and in the present case, the patient's condition improved transiently on oral medication of aspirin, but we lost the contact with him afterwards.

We report an unusual case of necrobiosis lipoidica with prominent cholesterol clefts in a 36-year-old man who had developed multiple, 0.5~5cm in diameter, round to oval-shaped erythematous plaques on both shins for over 3 years. Laboratory findings showed the following; cholesterol, 250mg/dl; triglyceride, 208mg/dl; blood sugar level fasting/2-h postprandial, 101/92mg/dl; and other findings were within normal limits or negative. There was no paraproteinemia. The biopsy specimen showed various lymphohistiocytic granuloma with many giants cell in the mid and deep dermis, and septal fibrosis in the subcutaneous tissue. There were also extensive areas of necrobiosis with prominent cholesterol clefts mimicking necrobiotic xanthogranuloma.

We report a case of actinic granuloma in a 70-year-old woman with diabetes mellitus. Several annular lesions developed in both shins and persisted for five years, and similar lesions developed later mainly in sun-exposed areas. Histopathological study from the annular plaques of the shoulder showed actinic granuloma composed of numerous giant cells with disappearance of elastic fibers. Histopatholoc finding from the shin showed actinic granuloma of several foci of necrobiosis. From this case, we observed two different patterns of actinic granuloma in the same patient.

A 70-year-old woman with an 8-year history of systemic sarcoidosis developed round, red-brown eruptions, with central atrophic lesions on her lower legs. The features of the biopsy specimen resembled those of necrobiosis lipoidica (NL), but although necrobiosis was present there were well-formed non-necrotizing granulomas in the dermis. The histological diagnosis was cutaneous sarcoidosis. Systemic sarcoidosis presenting with NL has rarely been reported. The histological features of cutaneous sarcoidosis sometimes mimic those of other granulomatous diseases, including NL and granuloma annulare, which are difficult to distinguish. We discuss the novel association between sarcoidosis and other granulomatous diseases.

Palisaded neutrophilic and granulomatous dermatitis (PNGD) is an uncommon skin eruption associated with immune-mediated connective tissue diseases such as rheumatoid arthritis, lupus erythematosus, and Behcet's disease. This condition is also described as Winkelmann's granuloma, linear subcutaneous bands, rheumatoid papules, rheumatoid neutrophilic dermatitis, interstitial granulomatous dermatitis with cutaneous cords and arthritis, or Churg-Strauss disease. PNGD shows variable clinical manifestations and is characterized histopathologically by step pattern of early leukocytoclastic vasculititis, progressing to form palisaded granulomatous inflammation, and surrounding zones of necrobiosis in the later stages. We report a 66-year-old woman with multiple skin nodules, who had concomitant rheumatoid arthritis. Histopathologic findings revealed palisaded neutrophilic and granulomatous dermatitis.

A 29-year-old woman had multiple, umbilicated papules on her fingers for 2 months. Skin biopsy specimen showed transepidermal perforation filled with plug of cellular debris, degenerated collagen and mucinous material. In the dermis, there were necrobiosis and peripheral palisading of mononuclear cells. Special stainings including masson's trichrome, alcian blue, acid orcein, and PAS showed necrobiotic collagen fibers and acid mucopolysaccharides on the necrobiotic zone and trasepidermal elimination canal. Topical application of 0.05% Clobetasol-17-propionate ointment improved her lesion.
