Thus, a benign fibro-osseous
lesion was diagnosed and follow-up was recommended.
The flexor tendons are encased in a fibro-osseous
tunnel and are particularly vulnerable to infection given their unique blood supply.
The 2 cases in which SJCRH pathologist deemed IHC unnecessary in discordance with the international pathologist were (1) an original diagnosis of embryonal rhabdomyosarcoma with an SJCRH final diagnosis of fibro-osseous
lesion and possible fracture with secondary aneurysmal bone cyst and no evidence of rhabdomyosarcoma in the reviewed material; and (2) an original diagnosis that included the following differential diagnosis: possible extranodal histiocytic sarcoma, synovial sarcoma, or rhabdomyosarcoma; whereas the SJCRH final diagnosis favored osteosarcoma.
16) However, other authors describe osteoma as a fibro-osseous
tumor; the process is represented in different phases, with fibrous dysplasia, ossifying fibroma, and, as the end stage, osteoma.
These features are those of a fibro-osseous
lesion with giant cells and were thought to be most in keeping with a central giant cell lesion, either a granuloma or a Brown tumour of hyperparathyroidism.
1-cm mass with a ground-glass matrix in the left zygoma, a finding that was consistent with a fibro-osseous
lesion of indeterminate malignant potential (figure 1).
The particular emphasis of the cranial work was on the following locations: where those cranial nerves cross the borders of tentorium cerebelli, as they pass through cavernous sinus, where the particularly vulnerable spot was, the fibro-osseous
canal beneath the posterior clinoid processes, at sutura petrobasilaris, and where those nerves enter the orbit through fissure orbital is superior.
The carpal tunnel is a fibro-osseous
tunnel compriesed of U-shaped bones bridged by the transverse carpal ligament.
Fibrous dysplasia (FD) is a congenital but noninheritable benign disorder in which medullary bone is replaced by fibro-osseous
tissue which causes distortion and overgrowth of the affected bone (1).
Fibrous dysplasia is a benign fibro-osseous
lesion, which may present in either monostotic or polyostotic forms.
Other conditions which cause a change in the relative volume of the tendon, or the fibro-osseous
canal also fall into this category.
, fibrous, and fibrocartilaginous forms have been described.
