fibrousFibrous dysplasia tissue that usually develops after healing of a skin injury. The tissue extends beyond the borders of the original wound, usually does not regress spontaneously, and tends to recur after excision.
As surgeon has mentioned below, a hernia is also possible. I would suggest a referral back to a plastic surgeon to see if treatment for a keloid is to be considered (i.e. repeat surgery or possible steroid injection).
