The human papillomavirus family is composed of a large number of different and variably related types, each of which is associated with a characteristic set of epithelial lesions. Each of the many identified types of human papillomavirus have shown considerable specificity of different anatomical sites and different characteristic lesions. HPV 6 and 11 are frequently associated with benign condylomas, while HPV 16 and 18 are associated with malignant progression and cervical cancer. The genome of papillomaviruses is composed of a circular double stranded DNA. Various open reading frames (ORFs) are located on only one DNA strand. The coding strand contains from 8 to 10 translational ORFs. Among them, only 6 to 8 were designated as early and 2 as late. The role of HPVs 16 and 18 in uterine cervix carcinoma has been well-documented, but their contriobution to carcinogenesis of other neoplasias is still questionable.
