Benign bone growth: Osteoma is a growth of new bone usually growing on or within another piece of bone, typically the skull. The lesion is considered benign. When this tumor grows on other bone it is known as "homoplastic osteoma"; when it grows on other tissue it is called "heteroplastic osteoma". The primary variant is known as an osteoid osteoma which has a center of growing cells, called a nidus, surrounded by a hard shell of thickened bone. The osteoid osteomas tend to be small—less than 1.5 cm in size and they may occur in any bone in the body appearing in patients between the ages of 4 and 25 years old
