Excellent response of basal cell carcinomas and pigmentary changes in xeroderma pigmentosum to imiquimod 5% cream.

Xeroderma pigmentosum (XP) is an autosomal recessive disease in which patients have a 1000-fold increased risk of developing cutaneous neoplasms. Management of patients with XP is a difficult therapeutic challenge as they usually present with many cutaneous malignancies and continue to form skin tumours at a high rate. We describe a 19-year-old woman with XP who had been previously treated with many different therapeutic approaches. She had an excellent clinical response of her multiple small pigmented basal cell carcinomas and pigmentary changes using imiquimod 5% cream with only minor side-effects.
