Hello. This is probably one of the many benign skin nodules dogs can get. If it has been relatively quiet for the past several years, it is not likely a something neoplastic or of great concern. If it grows, changes color again, or begins to bleed, then it might be a good idea to just have it removed. Some benign growths can turn cancerous, although this is pretty rare. Do show this to your veterinarian at your next visit & thanks for contacting Petco Pet Education Center, formerly Petcoach.
