osteoid

 [os´te-oid]
1. resembling bone.
2. the organic matrix of bone; young bone that has not undergone calcification.
osteoid osteoma a benign hamartomatous lesion of cortical bone in young persons. There are small sclerotic bone-forming areas visible on technetium diphosphate bone scan. The small central nidus produces large amounts of prostaglandin. There is often night pain, which may be responsive to nonsteroidal antiinflammatory drugs. Lesions may be excised in toto or may be treated with nonsteroidal antiinflammatory drugs, and often undergo involution in 5 to 7 years.

Angiogenesis was reduced in all the groups by comparison with the second week, and osteoid was hardly ever found in the cases (figure 6).
Recurrence rate is less than 10% with power burr.8 A new non-invasive radiation-free method is under observation - magnetic resonance guided focussed ultrasound ablation technique - which focuses ultrasound waves on osteoid osteoma.

(3) retrospectively reviewed patients with benign bone lesions and documented that 30% of the diagnosable lesions were osteochondromas, 28% bony cysts, 12% en-chondromas, 11% osteoid osteomas, and 6% non-ossifying fibromas.
The neoplastic bone is eosinophilic when unmineralized (osteoid) and basophilic/purple if mineralized.
Foci of bone and osteoid formation were also seen (Figures 3 and 4).
