Nephrogenic fibrosing dermopathy in a patient with systemic lupus erythematosus and acute lupus nephritis.

Nephrogenic fibrosing dermopathy is a recently recognized skin disorder similar in appearance to scleromyxedema but without the systemic involvement. We describe a 14-year-old girl with new-onset systemic lupus erythematosus and acute lupus nephritis who developed on the lower extremities confluent hyperpigmented, woody, indurated plaques that contained groups of coalescing erythematous papules. Nephrogenic fibrosing dermopathy was diagnosed histologically. Possible etiologies are discussed.
