Histologically, it displays fibrous tissue with randomly oriented woven bone
Microscopic examination depicted an active production of osteoid and primitive woven bone
in a well-vascularized connective tissue stroma.
Areas of new woven bone
and cartilage were then traced.
Heterotopic bone is characterized by spicules of woven bone
arranged in parallel arrays surrounded by fibroblasts that enclose a less calcified osteoid.
Fibro-osseous lesions are disorder of bone in which immature matrix of woven bone
replaces matrix of normal bone.
In the CS-PRP group, newly formed woven bone
connected the host bone edges of the defect site [Figure 2]a, and the bone marrow cavity was partially formed [Figure 2]b, which corresponds to the radiographs.
Osteiod Osteoma consists of woven bone
and osteoid, which is surrounded by halo of reactive sclerotic bone, having less than 1.
WHO definition is "benign cystic lesions of bone composed of blood filled spaces separated by connective tissue septa containing fibroblasts, osteoclast type giant cells and reactive woven bone
A layer of new woven bone
was deposited at the host bone-implant interface along both sides and bone ingrowth was seen into the implant.
37) The presence of intralesional, delicate spicules of woven bone
gives the affected segment a "ground-glass" appearance.
The World Health Organization has defined it as an intraosseous lesion consisting of cellular fibrous tissue that contains multiple foci of hemorrhage, aggrega-tions of multinucleated giant cells and occasionally trabeculae of woven bone
Osteoblastomas are composed of an abundantly vascular connective-tissue stroma with active production of osteoid and primitive woven bone
