Once lesions occur, the clinical course varies. Most lesions continue to grow for weeks to months and others grow for years. Growth is usually slow, but keloids occasionally enlarge rapidly, tripling in size within months. Once they stop growing, keloids do not usually cause symptoms and remain stable or involute slightly.
