I am sharing an image of a mole on my mother's back. She has been having this mole on her back for the past 8-9 years. It has increased in size over a period of such years. There is itching and when rubbed the skin of it ruptures and bleed and then a bruise develops over it which starts itching when it gets healed. I have applied betadine liquid to this area and covered it with tape. Kindly see the images. Is this a normal mole or is there some malignancy involved? Kindly answer.
