Nephrogenic fibrosing dermopathy.

An adult female patient on hemodialysis for chronic renal failure presented with large, brownish, and indurated plaques with bound-down skin on both lower limbs and abdomen along with difficulty in movement of the legs. Histopathological features revealed thick collagen bundles admixed with mucin and intercalating spindle-like cells characteristic of nephrogenic fibrosing dermopathy (NFD). Immunohistochemical study showed prominent CD68 positivity and weak CD34 positivity suggesting that the plaques were more than 20-weeks old.
