Xeroderma Pigmentosum | Health Dictionary

A rare disease in which DNA repair mechanisms fail, rendering the skin especially vulnerable to damage from ultraviolet light (see ULTRAVIOLET RAYS (UVR)). Extreme photosensitivity begins in infancy; later, marked freckling occurs and premature CARCINOGENESIS in the skin usually leads to early death. There may also be neurological complications.
