[Nephrogenic fibrosing dermopathy. Report of two cases]

Nephrogenic fibrosing dermopathy is a recent designation to describe cutaneous findings in patients with renal disease who developed scleromyxedema-like skin lesions with thickening and hardening of the skin. These skin lesions appear mainly after hemodialysis or renal transplantation but their origin is still unknown. We report a 63 years old male on hemodialysis and 56 years old male on peritoneal dialysis, who developed a nephrogenic fibrosing dermopathy that was confirmed by pathology and immunohistochemistry with monoclonal antibodies against CD34).
