a little bigger than a quarter on my back and I had it since I was about 10 years old... I am now 23 and it has bothered me all of these years. I just want to make sure that it would be safe
as it is a melanocytic nevus that develops a surrounding circle of depigmentation. It may develop cellular atypia and if you get a tattoo over the nevus, you may never come to know of the skin changes that may occur with the nevus which may be due to underlying malignancy.
Hope it helps. Take care and please do keep me posted on how you are doing or if you have any additional queries. Kind regards.
