Long mole on the face can go to the hospital to hang a dermatology department. A long mole on the face is also called a mole, and medically it is called a pigmented mole. Clinically, it can be divided into borderline mole, mixed mole and intradermal mole. The nevus cells of intradermal nevus are located in the dermis, which are generally tumors protruding from the skin surface, and the hair can penetrate the tumor surface. Both nevus and mixed mole are flat papules, and nevus cells are located at the junction of dermis or between dermis and epidermis. Specific treatment, you can choose laser, trichloroacetic acid freckle or surgery and other treatment methods. The size of the rash is relatively large, so you can choose surgical resection and make further pathological diagnosis after resection. Moles with large needle tip or small volume can be removed by laser. We usually look at the size of a mole. If it is less than 2 mm, you can go to the laser department and burn it by laser cauterization. Laser Dot mole may leave a sunken scar, which is not obvious when the mole within 2mm comes out, but if it is more than 2mm, the sunken scar may be obvious when the laser comes out. So if it's more than two millimeters, you need to go to the plastic surgery department. Pigmented nevus was removed by surgery, and our face was healed by fine plastic suture, leaving only a thin scar. Compared with laser, this method leaves smaller scars. Then there is another situation. If the mole is particularly deep, no matter how old it is, it needs to be removed by the plastic surgery department. Because some moles are particularly deep, the laser may not fall off at once, and he may relapse through surgery.
