We all know that a wart is a skin growth, with a dense structure and a rough surface. It rises above the skin in the form of a small rounded nodule. However, there is another type of neoplasm that differs in its structure and localization – these are subcutaneous warts.
Outwardly, they look like corns, but the nature of origin and structure are completely different. As a rule, such growths appear in two places – on the foot, as well as under the nail or near it. Despite external differences and localization, subcutaneous and ordinary warts have a common cause.
Why do subcutaneous growths appear
The skin is a kind of barrier to the penetration of infections, however, if there is damage on it, viruses can easily penetrate through them into the human body.
Most often, this is how HPV infection occurs. Once inside, the papilloma virus integrates and changes the DNA of epidermal cells, provoking their rapid, uncontrolled division. It is papillomavirus infection that is responsible for the fact that an epidermal or subcutaneous growth is formed on the human body.
The virus is transmitted in three ways – contact-household, sexual, and from mother to child (at birth). Once in the body, the infection does not immediately appear, the incubation period from 1 month to several years – it all depends on the state of the immune system. To activate HPV, a sharp decrease in immunity is required.
Provocateurs of the disease can be:
- Frequent infectious, chronic diseases;
- Using other people's hygiene or household products;
- Non-compliance with hygiene;
- Excessive sweating of the feet, hands;
- Hormonal imbalance;
- Endocrine disorders;
- Frequent injuries, cracking of the skin;
- Wearing the wrong shoes.
Types of subcutaneous neoplasms
The wart under the skin can be of two types – the plantar (it is also called the spine) and the subungual. The reasons for their formation are excessive friction, pressure, sweating against the background of the active HPV phase.
Plantar growth – localized on the feet, hurts when walking. The structure of such a wart is characterized by the presence of roots that are able to grow into deep tissues. The neoplasm practically does not protrude above the skin level, most of it is located inside it. Contributes to the growth of the build-up wearing narrow shoes made of hard materials.
Subungual wart – such growths do not have roots. There are no painful sensations. The danger is that, growing, these neoplasms lead to the destruction of the nail plate. In addition, without timely treatment, secondary infection is possible, which further exacerbates the problem.
Symptoms of subcutaneous growths
At the initial stage of development, it is quite problematic to recognize a subcutaneous wart on the foot – it has an indented appearance and does not manifest itself in any way. Later, the affected area begins to change:
- The upper layer of the wart becomes rough;
- The surface is keratinous, flaky;
- The growth has clear edges;
- Dark patches (soldered vessels) are visible inside it;
- Itching often occurs, a slight burning sensation at rest;
- When walking, pressing pain is felt.
Around the growth, inflammation, swelling is possible. Often, one neoplasm becomes the cause of multiple seeding, spreading infected cells to healthy tissues.
The structure of the wart under the skin is very dense, its roots go into the deep layers of the skin and can grow, filling up the entire epidermal space of the foot, even reaching the muscle tissue – in this case, due to severe pain, a person can’t step on his leg at all.
The subungual growths do not have such pronounced pain. You can recognize them by the following signs:
- Dryness appears first;
- The skin begins to peel off, becomes rough;
- Then small rounded growths form;
- They can be single, but with multiple seeding (which happens often) merge into a single conglomerate;
- Prolonged inaction leads to deformation, thinning of the plates;
- Nails are stratified, and subsequently destroyed.
Treatment of subcutaneous neoplasms is carried out comprehensively. Therapy consists in hardware removal, as well as taking antiviral, immunostimulating drugs (after all, these growths are of viral origin and appear as a result of a decrease in immunity).
There are several ways to get rid of a wart:
- Laser destruction – a wart is burned along with the root. The required depth of exposure is determined by the doctor. In the process of removal, healthy tissues are not damaged. Bleeding is impossible, because coagulation of blood vessels occurs simultaneously. For the same reason, infection is excluded;
- Radio wave removal – under the influence of high temperatures, the growth is evaporated along with the root. In its place, a crust forms, which protects against infection and allows the wound to take on new healthy skin. Healing lasts 10-14 days, no obvious traces remain;
- Electrocoagulation – cauterization of the wart with high-frequency current. This method is most often used to remove plantar growths. It is highly effective, but at the same time there is a risk of scarring of tissues;
- Cryotherapy – this method is suitable for elimination without root neoplasms, such as subungual warts. The growth is frozen with nitrogen, after which it dies.
It is important not to tear off the formed crust after the removal procedure, rejection should occur on your own, so you will avoid the possible infection and scarring of tissues.
