Flesh nevi can be removed. However, the cause of nevus formation is still unclear, and there is still a possibility of recurrence after removal. A nevus is not really a mole, but a localized proliferation of fibrous connective tissue, which is medically called a soft fibroma, commonly known as a dermatome. It is usually found on the eyelids, neck, armpits and groin, etc. It is a small, flesh-colored, pink or brown colored growth that protrudes from the skin surface. If the nevus is less than 3 mm in diameter, it can usually be removed using a CO2 laser or high frequency ionization. Normally, the treated area will crust over within a week and will simply fall off on its own. For larger nevi, it may be relatively difficult to remove after laser treatment, so it is recommended to go to the dermatology department or plastic surgery department of a regular hospital for surgical removal and pathological examination to clarify its benign or malignant nature. If the patient’s nevus recurs again, continued treatment is sufficient. During the process of nevus removal, patients should pay attention to the treatment area not to get wet and avoid direct sunlight, so as not to cause infection or induce the possibility of nevus recurrence.
