Human Papillomavirus on the Skin: What It Looks Like and Where It Appears

You have noticed a small firm bump on your skin or a strange growth on a mucous membrane and want to understand what it is. Human papillomavirus can cause such changes, and they do not always mean something serious. Let us calmly go through what HPV looks like on different parts of the body and in which cases a conversation with a doctor should not be delayed.

What is human papillomavirus

HPV is a group of more than 200 related viruses, some of which are transmitted sexually. Most people have encountered the virus, and usually the immune system keeps it under control: the infection clears on its own and does not cause health problems. Viruses are divided into low-risk and high-risk types. Low-risk types can cause warts on the genitals, around the anus, in the mouth or throat. High-risk types can remain in cervical cells for years and lead to changes that, without monitoring and treatment, may worsen over time. Infection itself is not the same as disease: what matters more is how the virus behaves and what changes it causes.

What HPV looks like on the skin and hands

Skin warts are firm, rough-to-the-touch growths. They occur on the palms, fingers, knuckles, and knees. The color is usually close to skin color; on dark skin they may look darker. Some warts are round and flat, yellowish, and there can be many of them. Clusters of warts merging into patches of skin are often seen on the hands and feet. The virus is transmitted through close skin contact and via contaminated surfaces, and after infection several months may pass before a wart appears. Such growths are not dangerous in themselves, but they can be painful or bothersome.

HPV on the pubis, vulva, and labia

On the genitals and around the anus, low-risk types can cause warts. A doctor usually recognizes such warts on examination. The appearance of any growths in this area is a reason to see a doctor to clarify the nature of the changes.

HPV on the lips and mucous membranes

Low-risk types can affect the mucous membranes of the mouth and throat, causing warts in these areas. Infection is possible not only sexually: the virus enters through microcracks in the skin, as well as through household contact and via objects. A growth on the lip, in the mouth, or in the throat should be examined by a doctor.

Anogenital papillomas and risks

Anogenital warts are registered in millions of cases worldwide each year. The main route of transmission is sexual, but a condom reduces rather than completely eliminates the risk, since the virus lives on the skin around. Self-infection during shaving or epilation is also possible. High-risk types are considered separately: they more often do not cause visible warts, but with many years of progression they are associated with changes in cervical cells and certain types of cancer. That is why monitoring and screening matter more than the appearance of the skin.

• Skin warts are not harmful but may itch or hurt.
• Anogenital warts can be painful.
• High-risk HPV types often proceed without symptoms.
• Skin changes after infection do not appear immediately, sometimes after months.

How the diagnosis is confirmed and when to see a doctor

A doctor usually recognizes warts on examination. To assess the condition of the cervix, screening tests are used — cytology (Pap test), an HPV test, or both, and colposcopy is offered if needed. You should see a doctor if you are concerned about any new growth on the skin, if a wart bleeds or changes appearance, if it is very large or painful, and also for growths on the face and genitals. Anogenital warts are examined by a gynecologist or a dermatovenereologist.

The appearance of a wart or papilloma is not in itself a reason to call an ambulance. Call 103 or 112 if a life-threatening condition occurs, such as severe bleeding or loss of consciousness.
