You'd better go to the plastic surgery department to see a doctor. After resection, it will be repaired with local skin flap, and the color will be better, but there will be scars around it after operation.

(Dr. Tang Hongtai of Shanghai Changhai Hospital solemnly reminds: Because I can't see the patient face to face, I can't fully understand the condition. The above suggestions are for reference only. Please go to the hospital for specific diagnosis and treatment under the guidance of a doctor! )
