Warthttps://en.wikipedia.org/wiki/Wart
Warts are small, rough papules that are similar in color to the surrounding skin. They usually cause no other symptoms, except when they occur on the soles of the feet, where they can be painful. While they most often appear on the hands and feet, they can affect other locations as well. One or many warts may develop, but they are not cancerous.

Warts are caused by infection with a type of human papillomavirus (HPV). Risk factors include using public showers and pools, having eczema, and a weakened immune system. The virus is thought to enter the body through slightly damaged skin. Several types exist, including common warts, plantar warts, and genital warts. Genital warts are often sexually transmitted.

Warts are very common; most people become infected at some point in their lives. The estimated prevalence of non‑genital warts in the general population is 1–13%, and they are more common among young people. The estimated prevalence of genital warts in sexually active women is 12%.

Various treatments can be used, including topical salicylic acid and cryotherapy. In otherwise healthy individuals, warts typically do not cause significant problems.

○ Treatment ― OTC Drugs
Among salicylic acid formulations, a brush‑type preparation is preferable for long‑term use. When applied, the medication can spread, so it should be applied slightly narrower than the lesion. Older warts are often deeper and may require months of treatment. Cryotherapy is another option, but it also may require multiple sessions over time. If the wart is not removed completely, it can spread further through the wound.

  • A large number of warts are present on the big toe
  • Multiple black dots are important findings that suggest warts.
  • Verruca vulgaris ― First toe
  • Verruca filiformis ; Warts around the eyes appear small. Typical case.
  • A filiform wart on the eyelid
  • When warts appear around the genitals, they are diagnosed as condyloma.
  • This is a typical plantar wart. The absence of a callus on the toe is an important finding. When a callus‑like lesion appears in someone with no prior history of callus formation, it is usually a wart.
  • The photo shows a plantar wart after treatment with salicylic acid.
  • Since it is a symmetrical lesion, callus should also be considered. The callus on the heel suggests that the patient may have walked a lot.
  • Plantar wart

It is a comprehensive and systematic evidence-based guideline and we hope this guideline could systematically and effectively guide the clinical practice of cutaneous warts and improve the overall levels of medical services.

Skin diseases like actinic keratosis, solar lentigo, seborrheic keratosis, viral wart, molluscum contagiosum, dermatofibroma can be safely treated with cryotherapy (=freezing).
 Molluscum Contagiosum and Warts 12674451
Both molluscum contagiosum and warts are caused by viral infections. Molluscum contagiosum usually goes away on its own without causing further problems, but it can be more severe in people with weakened immune systems. Although lesions tend to disappear by themselves, treatment options like removal or immune system support can speed up recovery and reduce the risk of spreading the virus. Warts, caused by the human papillomavirus, lead to thickened skin growth. They come in different types depending on where they appear on the body. Treatment options include removal, medication, or immune system therapy.
