A wide variety of HPV types can cause genital warts, but types 6 and 11 together account for about 90% of all cases. [35] [36] However, in total more than 40 types of HPV are transmitted through sexual contact and can infect the skin of the anus and genitals. [4] Such infections may cause genital warts, although they may also remain asymptomatic.
Genital warts, histopathologically, characteristically rise above the skin surface due to enlargement of the dermal papillae, have parakeratosis and the characteristic nuclear changes typical of HPV infections (nuclear enlargement with perinuclear clearing). DNA tests are available for diagnosis of high-risk HPV infections.
HPV DNA can be found in up to 87% of vulvar intraepithelial neoplasia (VIN) and 29% of invasive vulvar cancers; HPV 16 is the most commonly detected subtype in VIN and vulvar cancer, followed by HPV 33 and HPV 18. [15] VIN is a superficial lesion of the skin that has not invaded the basement membrane—or a pre-cancer. [16]
Papillomaviridae is a family of non-enveloped DNA viruses whose members are known as papillomaviruses. [1] Several hundred species of papillomaviruses, traditionally referred to as "types", [2] have been identified infecting all carefully inspected mammals, [2] but also other vertebrates such as birds, snakes, turtles and fish.

Epidermodysplasia verruciformis (EV) is a skin condition characterised by warty skin lesions. [1] It results from an abnormal susceptibility to HPV infection (HPV). It is associated with a high lifetime risk of squamous cell carcinomas in skin. [1]
The cause of CIN is chronic infection of the cervix with HPV, especially infection with high-risk HPV types 16 or 18. It is thought that the high-risk HPV infections have the ability to inactivate tumor suppressor genes such as the p53 gene and the RB gene, thus allowing the infected cells to grow unchecked and accumulate successive mutations, eventually leading to cancer.
“HPV has dotted my life with grief, medical trauma and immense pain,” Hindes tells Yahoo Life. “It cost me my ability to have another child and potentially a far different career.”
