Granuloma annulare: direct immunofluorescence study.
Direct immunofluorescence studies were carried out in eleven specimens of granuloma annulare. The results (in all cases) indicate the presence of focal deposition of fibrin, localized primarily in the intervascular portion of the dermis, corresponding to the granulomatous and necrobiotic areas. These findings implicate the cellular mechanism of delayed hypersensitivity with focal involvement of the clotting system in the development of granuloma annulare lesion.

Necrobiotic xanthogranuloma with paraproteinaemia.
A 66-year-old man with necrobiotic xanthogranuloma associated with paraproteinaemia is described. He also had long-standing normolipaemic plane xanthomata. Treatment was with melphalan 0.15 mg/kg body weight/day. Initially, three 5-day courses were given at 4-weekly intervals but a fourth course was necessary after a further 4 months because of a deterioration in both his skin and associated systemic symptoms.

Clinicopathologic features of ulcerative-atrophic sarcoidosis.
BACKGROUND: Sarcoidosis is a chronic granulomatous disease of unknown etiology. Cutaneous disease is common and includes two clinicopathologic categories: granulomatous infiltration or a reactive phenomenon. In the granulomatous infiltrative group, clinical manifestations can be variable. Ulcers in sarcoidosis are uncommonly recognized and have been categorized previously under the rubric of atrophic, necrobiosis-like, or ulcerative sarcoidosis. PATIENTS AND METHODS: We evaluated retrospectively sarcoidosis patients presenting to the Johns Hopkins Department of Dermatology between June 1989 and May 2002. Multiple skin biopsies were performed for histopathologic evaluation. Investigation for extracutaneous manifestations, including routine serologic assays, chest radiography, pulmonary function tests, electrocardiogram, and angiotensin-converting enzyme level, and referral for ophthalmologic examination were performed in all patients. RESULTS: Of 147 consecutive patients presenting with cutaneous sarcoidosis, seven demonstrated ulcerative-atrophic sarcoidosis lesions. All patients were African-American (five females and two males). All patients had ulcers surrounded by atrophic necrobiosis lipoidica-like plaques on the pretibial areas. All patients had other mucocutaneous manifestations of sarcoidosis, with the majority having evidence of internal disease. Combined immunosuppressive and immunomodulatory therapy was effective in controlling the cutaneous manifestations of all patients with ulcerative sarcoidosis. CONCLUSIONS: The ulcerative variant is a poorly defined subset of cutaneous sarcoidosis. Trauma, superimposed on atrophic plaques, appears to be the principal mechanism of this rare variant of cutaneous sarcoidosis.
Annular elastolytic giant cell granuloma causes an irreversible disappearance of the elastic fibres.
A 67-year-old man presented with grouped red papules with a smooth surface coalescing to relatively well-demarcated plaques on his left thigh, in the axillae and on the lateral parts of the trunk. The plaques were growing slowly, and the older ones had a frilled surface. A skin biopsy showed a zone of disappearance of the elastic fibres with a rim of giant multinuclear cells with fragments of the elastic fibres in their cytoplasm. This finding is typical of annular elastolytic giant cell granuloma (AEGCG). After corticosteroid therapy, the inflammation resolved, causing the frilled surface of the lesions due to the disappearance of the elastic fibres. Remission of the skin lesions lasted for 1.5 years. A second skin biopsy taken from the site of the previous lesion showed the absence of the elastic fibres, thus their phagocytosis was irreversible.

Cutaneous manifestations of diabetes mellitus in children.
This article reviews skin changes occurring in diabetic children. Skin changes may be related to metabolic alterations associated with diabetes. Others may be manifestations of macro or microvascular disease. Insulin injections, required for management of most diabetes in the pediatric age group, may also cause cutaneous changes. There remain several cutaneous abnormalities which are observed with increased frequency among diabetics, the significance of which is unknown. The skin is a potentially invaluable tool for understanding certain diabetic complications; however, the value of observations and experimental data relating to cutaneous changes in diabetics depends upon documentation of the type of diabetes mellitus employing the currently accepted classification system.
Annular elastolytic giant cell granuloma.
Annular elastolytic giant cell granuloma (AEGCG) is a clinical and histological entity, which has been described previously in various different terms. Knowledge of AEGCG is of importance, since its misdiagnosis may lead to improper therapy; e.g. longterm tuberculostatic or corticosteroid treatment. In the present paper two patients with typical AEGCG are described and the clinical and histological differential diagnosis is discussed in detail.
