Those factors promote a set of skin abnormalities such as keratosis, hyperpigmentation, tumors in areas exposed to sunlight, and ocular and, eventually, neurological disorders. In the present review, we summarize the main clinical features related to a case of xeroderma pigmentosum in a man who was not diagnosed until he was 45 years old. Keywords: xeroderma pigmentosum, DNA repair-deficiency disorders, ultraviolet rays
