Flat warts, also called flat warts or verruca plana, are caused by the human papillomavirus (HPV). Flat warts are benign, innocent swellings. The biggest problem is that most people who have visible warts are ashamed of it. Flat warts are smooth and flat and relatively small. They are normally a few millimeters in size. Often these are light brown in color or skin color. Often they are on the face, arms or legs. Flat warts can be removed in various ways, including with nitrogen or cream.
What are flat warts?
Warts are caused by the human papillomavirus (HPV). Flat warts are mainly caused by HPV type 3, 10, 28 and 49. The virus causes a thickening of the upper skin layer. Flat warts are very flat, smooth and small in size: 2-5 mm in size. However, they can be present in large quantities. They are usually painless and disappear spontaneously, sometimes after a few months to a maximum of 2 years. This is related to the production of antibodies against the specific virus. Before they disappear, they often first turn red as a result of an inflammatory reaction.
Who will suffer from it?
Warts can occur in people of all ages, but young people between the ages of 12 and 16 are most often affected. It is estimated that 20% of school children and about 10% of the general population have warts. People with weakened immune systems are more likely to develop warts.
Risk factors verruca plana
It is mainly young people who suffer from it, because they often have cuts or scratches on their skin and come into close contact with other young people. Crabs on acne spots in the face can also cause wounds, which can provide an opportunity for HPV. People with a weakened immune system due to chronic diseases, chemotherapy, radiotherapy, drug use or other factors also have a higher risk for HPV. Poor hygiene can also increase the risk of warts.
Skin irritation due to shaving is probably one of the main causes of flat warts. They often manifest themselves as a swarm with several, sometimes dozens, to a hundred, very superficial warts.
