[Nephrogenic fibrosing dermatosis: From clinic to microscopy].

Nephrogenic systemic fibrosis is a rare entity occurred in patients with renal failure. It is related to toxicity to gadolinium, which is used as a contrast agent in magnetic resonance imaging. Clinic manifestations are variable. They begin by a thickening of the skin in the lower limbs and extending to the upper limbs. We report a new case of nephrogenic systemic fibrosis where cutaneous lesions begin in the upper right limb as indurated and ulcerated nodules. The diagnosis is histological.
