Large moles that grow naturally can usually be spotted off by methods such as laser, but specific treatments have to be chosen according to the actual situation of the patient. Laser mole spotting is generally applicable to moles that are small in area and size and without inflammation. First, the mole and the surrounding skin are sterilized, and then epidermal anesthesia is administered with lidocaine, etc. After the anesthesia is completed, the mole can be spotted with the laser. For larger moles, the laser may not be able to remove them completely at one time, so you can do it again after the scabs fall off. Remember not to go too deep, as it may cause scarring or irritation to the mole itself, leading to malignant changes. If the congenital pigmented nevus is a junctional nevus, or the color of the nevus has deepened and increased in size recently, or there is inflammation on the surface of the pigmented nevus, then it should be surgically excised to prevent it from malignant changes. It is recommended that patients with large naevi should go to regular hospitals for timely consultation, and choose the appropriate way of treatment under the doctor’s guidance after a clear diagnosis.
