title: Nephrogenic fibrosing dermopathy in a renal transplant recipient with tubulointerstitial nephritis and uveitis.
abstract: We report a patient with nephrogenic fibrosing dermopathy. He had chronic renal failure with arthritis, uveitis and histologically severe tubulointerstitial nephritis for which he received a renal transplant from a family relative. After an episode of acute renal failure with the transplant he developed painful, erythematous, firm papules and plaques with geographic borders on the legs, anterior thorax and elbow. A skin biopsy revealed increased fibroblast and collagen fiber content of the dermis and subcutaneous septae. Mucin deposition, sparse smooth-muscle-actin-positive cells and an increased number of CD34-positive cells in the deep dermis were found. After several weeks of hemodialysis, the lesions changed from an inflammatory to a purely sclerotic phase. The fibrocyte, a recently described circulating cell type, that is deposited in scar tissue may be involved in the pathogenesis of this novel pseudosclerodermatous skin disorder.
