title: [Nephrogenic fibrosing dermopathy].
abstract: A 58-year-old man with renal insufficiency, who was being treated by haemodialysis, developed progressive skin lesions. He had thickening and hardening of the skin at the extremities and swelling of the toes and fingers with flexion contractures. His face was not affected. Laboratory evaluation was unremarkable and a skin biopsy [table: see text] showed an increase of collagen and mucin, without an inflammatory infiltrate. These clinical features resemble a recently reported new disorder: nephrogenic fibrosing dermopathy. This disorder manifests as scleromyxedema-like cutaneous skin lesions without associated paraproteinemia, occurring in the setting of renal disease. The histopathologic features of nephrogenic fibrosing dermopathy, i.e. thickened collagen and mucin deposition, are unique. The incidence, prevalence and cause of the disease are unknown and there is currently no effective treatment. The Centers for Disease Control and Prevention (CDC) in the USA are calling on physicians who have encountered patients suffering from this type of lesions to contact the CDC for an intended control study.
