Skin and diabetes.

Skin manifestations associated with diabetes mellitus are common and, with close scrutiny, can occur in most, if not all, patients. Little information is available on what common pathophysiologic thread is responsible for the skin manifestation and diabetes. Although controlled studies are lacking, a recognition of the skin manifestations, treatment, and prognosis will help patients and their caregivers to understand treatment alternatives more clearly.

[Bilateral necrobiotic xanthogranuloma of the eyelids with associated paraproteinemia: Case report and review of literature].

BACKGROUND: Necrobiotic xanthogranuloma is a rare disorder which predominantly affects the periorbital region and is frequently associated with paraproteinemia and lymphoproliferative diseases. PATIENT AND METHODS: A 49-year old woman presented with bilateral, yellowish, subcutaneous lesions involving all four eyelids. These lesions have developed over the last year. Additionally, similar skin lesions developed on the trunk and the lower extremities. Two years ago, the patient had a bilateral episcleritis. An incisional biopsy was taken form the lesion. In addition, we reviewed the literature concerning similar cases. RESULTS: Histologic examination revealed a granulomatous process consisting of histiocytes, foamy cells, multinucleated giant cells (touton- and foreign body-type) and associated with necrobiotic collagen and cholesterol clefts. General examination revealed the presence of a paraproteinemia of the IgG-typ associated with a hyperlipidemia. The patient was treated with a low dose chemotherapy which resulted in improvement of signs and symptoms. We could identify in the literature 75 similar cases. The mean age of those patients was 53 years. CONCLUSION: The clinical and histologic findings in our patient were typical for a necrobiotic xanthogranuloma with associated paraproteinemia. The most favorable treatment response has been reported with low doses of systemic administered chemotherapeutic agents in combination with radiation therapy; however, the mortality due to underlying diseases is high.

Necrobiotic xanthogranuloma without periorbital involvement: an ultrastructural investigation.

A case of necrobiotic xanthogranuloma without typical periorbital involvement is described at the ultrastructural level. The patient, a 58-year-old Italian man, presented in 1995 with a brief history of nodulo-papular lesions commencing on the lower limbs, and mild paraproteinemia. During 6 years of follow-up, anemia, neutropenia with marked lymphopenia, and increased ESR were found, while serum cholesterol and triglyceride levels decreased from hyper to hypo values. Systemic diseases, such as diabetes, malignancy, or extracutaneous lesions, often associated with NXG, have not developed. Conventional histology was distinctive for NXG, and immunohistochemistry confirmed that dermal histiocytes were not of Langerhans cell lineage. At ultrastructure, regeneration and degeneration ("regen-degen") features were observed in some individual deep dermal histiocytes, which have not been previously documented in the literature. Identification of giant histiocytes showing 'regen-degen'' aspects might prove to be a useful ultrastructural diagnostic marker for NXG.

Tissue reaction to metal on metal total hip prostheses.

The periprosthetic tissue reaction to polyethylene wear debris in metal on polyethylene total hip replacements is strongly implicated as the cause of osteolysis. This has led to a renewed interest in metal on metal total hip replacements. However, little is known about the role of wear debris in failures of these prostheses. Capsular and interface tissues from 9 long and short term metal on metal total hip replacement retrievals were studied to assess the tissue reaction around these prostheses. As compared with metal on polyethylene cases, the extent of the granulomatous inflammatory reaction and the presence of foreign body type giant cells was much less intense in metal on metal cases, likely because of the lower numbers and overall smaller size of metal wear debris particles. This may lead to a better transport of the particles from the joint tissues and a lower incidence of periprosthetic osteolysis around metal on metal hip replacement.
