Human papillomavirus DNA in conjunctival papilloma

A histologically proven conjunctival papilloma was examined for the presence of papillomavirus DNA by nucleic acid hybridization under relaxed conditions. It harbored papilloma-virus-specific DNA, which showed no detectable relationship with that of known virus types when tested under stringent conditions. This demonstrates that conjunctival papillomas are associated with more than one papillomavirus type. Viral diagnosis may turn out to be of prognostic value.
