Xeroderma pigmentosum: report of two cases and review of the literature.
J Pak Assoc Derma Jan ;22(3):279-82.

Xeroderma pigmentosum (XP) occurs due to molecular defects in the genes involved in nucleotide excision repair of ultraviolet-induced DNA lesions. Patients with XP have a risk of developing skin cancer about 1000 times more than that of the general population. We report a classical presentation in a 6-year-child and advanced squamous cell carcinoma in a 24-year old man.
