1, Osteoid production by a sarcoma is diagnostic of osteosarcoma.

2, Non-shaped matrix become the main part of the osteoid.

3, Focally, pink osteoid is present.

4, An osteoblastoma is just a big osteoid osteoma in the vertebra.

5, Conclusion The nidus of osteoid osteoma is so small, that the diagnosis is easy to miss. Both X-ray and CT scan can often demonstrate the central radiolucent nidus for ...

6, From osteoid to mature bone the color changed from orange-red, light blue to dark blue.

7, There are lots of osteoid tissue and chondral tissue in the tumor.

8, Objective:In order to comprehend the clinical feature of osteoid osteoma.

9, Objective To investigate the feasibility of osteoid callus allograft as a kind of bone healing promoting materials.

10, Summary of Background Data Curative treatment of osteoid osteomas entails complete intralesional excision of the nidus.

11, This is the central nidus of an osteoid osteoma composed of irregular reactive new bone.

12, Histological results showed the formation of osteoid and the deposition of calcium phosphate was more active in the test group than that of control group.

13, Osteoid is calcified by osteoblasts and during this process the cells become encased in lacunae within the calcified material and become osteocytes.

14, Objective To introduce the diagnosis and treatment of osteoid osteoma of the laminae with cortical destruction in children.

15, Results Aneurysmal bone cyst was found in 4 cases, giant cell tumor in 3 cases(accompanying aneurismal bone cyst 2 cases), ganglion, hamartoma, osteoid osteoma and lipoma in 1 case,[sentencedict.com](http://sentencedict.com/osteoid.html) respectively.

16, Results. In all 4 patients, Iso-C 3-dimensional computer navigation was successful in accurate localization of the osteoid osteomas.

17, Plenty of active osteoblasts, fibroblasts and mesenchymal cells were seen at the 2nd week, osteoid tissue formed, the proliferation of cartilage was active.

18, Pain is the main symptom and nidus is the key to the diagnosis of osteoid osteoma. CT scan is the best method to demonstrate the nidus.

19, Method. Iso-C 3-dimensional intraoperative navigation was used to localize osteoid osteomas of the spine in 4 patients.

20, Objective. To report on the efficacy of Iso-C 3-dimensional intraoperative spinal navigation in excising osteoid osteomas.

21, Methods A retrospective analysis was done in 16 patients with osteoid osteoma proved by surgical pathology.

22, They are very similar to osteosarcomas but unlike osteosarcomas, they do not produce the bony substance, osteoid.

23, Histologically, SRMS was characterized by the presence of large amounts of heavily hyalinized matrix, mimicking osteoid or chondroid tissue.

24, The bone tissue fabricated in RWV with two different seeded cell densities grew well. Osteoblasts in the scaffolds secreted much collagen fibers and formed mineralized nodules and new osteoid tissue.

25, At the distal part of femur in fetus age of 30 weeks, a cluster of lump-like osteogenic cell, osteoblast and basophlous osteoid filled among cells appeared at the secondary ossification center.
