However, unlike metaplastic carcinomas, osteoclastic giant cell breast carcinoma does not contain chondro-osseous
9) Bone marrow, which is adjoining the chondro-osseous junction, discharges [SDF.
Stimulation of chondrocyte hypertrophy by chemokine stromal cell-derived factor 1 in the chondro-osseous junction during endochondral bone formation.
REAH with chondro-osseous
differentiation have also been described.
respiratory epithelial adenomatoid hamartoma (COREAH) is an extremely rare type of hamartoma.
The absence of formation of normal primary spongiosa in the metaphysis, the presence of a thin seal of bone at the chondro-osseous
junction, with abnormal metaphyseal vascular invasion and arrest of endochondral growth, these findings suggest an uncoupling of endochondral and perichondral growth, and thus, dumbbell-shaped morphological structure of the osseous metaphysis seen in these patients.
Rarely, one finds cartilage or chondro-osseous
matrix within an osteoblastoma3 (Figure 15) in the absence of fracture, a finding once believed to be more in keeping with osteosarcoma.
border of the synchondrosis may be injured either as a chronic stress fracture or, less frequently, as an acute fracture.
2) Necrotizing OE is characterized by severe unilateral otalgia, which is deep and throbbing, and by persistent otorrhea, edema, granulation tissue, and bony erosion at the chondro-osseous junction in the external ear canal.
Otoscopy revealed that both external auditory canals were edematous, and extensive granulation tissue and exposed bone were seen at the chondro-osseous junction.
8-10] Rare instances of respiratory epithelial adenomatoid hamartoma with additional chondro-osseous
component have been described and may arise in a child.
Then the surface area of each of the sixbony components--the perpendicular plate of the ethmoid bone, the vomer, the sphenoid bone, the nasal process of the frontal bone, the nasal bone, and the palatine crest--was measured with a transparent grid calibrated in square millimeters, Then we calculated the contributions that each of these bones made to the total osseous surface area and the contribution that the total bony component made to the total chondro-osseous
septal surface area.
