Nephrogenic fibrosing dermopathy.
A 75-year-old woman with end-stage renal disease on hemodialysis presented with a 2-month history of progressive skin thickening of the lower extremities. A punch biopsy specimen showed plump fibroblasts entrapping collagen bundles and positive staining for CD34 and procollagen. These changes were consistent with a diagnosis of nephrogenic fibrosing dermopathy (NFD). Nephrogenic fibrosing dermopathy is a rare, sclerosing disorder in patients with renal failure, which may be mistaken for scleromyxedema. The etiology of NFD is unclear but may be associated with systemic involvement, antecedent surgical procedures, gadolinium, or an underlying hypercoagulable state. The treatment is limited, and only a few reported cases have shown remission after stopping dialysis in transient renal failure.
