Hi doctor, I have attached a photo for your reference. Is this sign dangerous? It started almost 20 years ago to become dark and it became to be lighter around 5 years ago. Two days ago, again I have noticed this transformation with a white surface and that is healing now. It is around 4 mm. Please clarify what it is.
