Nevus, medically known as pigmented nevus, has a clearer cause of development and is a developmental abnormality. It is recommended to observe closely and treat it through physical therapy or surgical excision if necessary.
1. Close observation: pigmented nevus is a benign growth composed of nevus cells, which is a benign tumor of the skin. If the nevus is relatively small, the patient does not have any uncomfortable symptoms, or it occurs in an area that is not susceptible to friction, it is recommended to observe it closely and generally does not require special treatment.
2. Physical therapy: if you feel that the pigmented nevus affects your beauty, you can use physical therapy, such as liquid nitrogen freezing, which can make the pigmented nevus necrotic, so as to achieve the therapeutic effect. Carbon dioxide laser and pulsed laser can also be used to treat pigmented nevi with a diameter of less than 2mm.
3. Surgery: Acquired nevus can be surgically removed if malignant changes are suspected, and pathological examination will be conducted. If the diameter of the nevus is more than 2mm, and if it affects the aesthetics, surgical excision can be considered. If the pigmented nevus occurs in the palm of the hand, soles of the foot, armpits, groin, shoulders, waistline and other parts of the body that are easily subject to friction, surgical excision treatment can be considered.
To summarize, pigmented nevi are relatively small and do not have any effect and can be closely observed. The appearance of burning, stinging, pain, enlargement, deepening of color, breaking and bleeding, etc., need to consider timely medical treatment. If it feels that it affects aesthetics, it can also be treated by physical therapy or surgical excision.
