[The essence of osteoid osteomas and osteoblastomas]
Abstract:
178 cases of osteoid osteomas and osteoblastomas collected during 35 years were studied morphologically and roentgenologically (angiography--28 cases). Clear-cut differences between these two lesions were revealed. The differences concerned: 1) the character of the border with the surrounding bone tissue; 2) the morphology of bone structures being chaotic in the osteoblastoma; 3) intensity of proliferation in the osteogenic tissue; 4) differences in the angiographic data. According to the author's opinion osteoblastoma is a blastomogenic process with destructive growth and intensive proliferation. Classical osteoid osteoma does not possess these properties and is the result of dysontogenetic development of the intraosseous vascular system.

Compact Bone
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...
