Ichthyosis is usually treated with laser therapy or freezing, and can also be treated with chemical corrosion. Ichthyosis is not a mole in nature, but actually a common wart, that is, human papilloma virus infection, that is to say, it is a type of HPV infection. After HPV infection, the virus stimulates the skin tissues for a long time on the surface of the skin, and then it will form a wart-like hyperplasia like warts, that is, ichthyotic nevus. This kind of growth tissue can be treated in different ways depending on the location, size and severity. If the size is small and the location is not on the face, you can consider treating it with freezing. If the location is on the face, it can be treated with a laser. If the initial warts are scattered individually, they can also be treated with caustic topical medications such as pediculin, acetic acid, etc. It is recommended to go to the dermatology department of the hospital.
