Background: Bony raised bumps on the forehead are not rare and are known as osteomas. They occur due to the development of normal bone under the periosteum of the non-hair bearing forehead.They are benign overgrowths of bone that are non-mobile.arge frontal osteomas that are more than just a bump on the forehead are rare.
