Conjunctival papilloma caused by human papillomavirus type 11 treated with systemic interferon in a five-year-old boy.

Conjunctival papilloma is a benign tumor of the conjunctival mucosa. In childhood, papilloma represents 7-10% of conjunctival tumors. Human papillomavirus (HPV)-6 and HPV-11 are the major HPV types responsible for conjunctival lesions. A five-year-old boy with a two-year history of conjunctival papilloma caused by HPV type 11 treated with systemic interferon alpha is reported and the literature is reviewed.
