They can also arise in association with Paget disease of bone, osteocartilaginous
exostosis, and bone trauma.
In the post-surgical histological examination of this structure, extrasynovial osteochondroma was reported in the IFP since the well-differentiated osteocartilaginous
tissue was surrounded by fibroadipose tissue and contained hemosiderin pigments.
Giant cell tumors of the larynx (GCTL) are extremely rare benign tumors arising in the osteocartilaginous
tissue of the larynx.
4) External otitis progresses from the external auditory canal to the temporal bone and the skull base via the fissure of Santorini and the osteocartilaginous
With prolonged cocaine inhalation, osteocartilaginous
necrosis may extend to the turbinates, paranasal sinuses and hard palate.
The radial head was being constantly forced into anterior, irreducible dislocation by this osteocartilaginous
mass on the proximal metaphysis of the ulna.
Eight of the nine cases included interposed structures similar to those reported in the literature, such as capsule and annular ligament, (9,11,17) but we did not find median nerve, (26) radial nerve, (6,8,10,12) osteocartilaginous
fragments, (7,13) or shortened ulna (27) as reported by others.
In keeping with the ossification, osteocartilaginous
tumors may occur in the larynx, including chondrosarcoma, chondroma, and, less frequently, osteoma, osteosarcoma, and giant cell tumor.
Dahlin and Unni considered the presence of an osteocartilaginous
exostosis insufficient reason for surgical extirpation because malignant transformation is so rare.
1) A plain radiograph can help to determine if the soft tissue tumor involves bone and to identify vascular calcifications within hemangiomas, ossification within myositis ossificans, and juxta-articular osteocartilaginous
masses within synovial osteochondromatosis.
Metaplastic carcinoma of the breast with osteocartilaginous
Microscopic examination revealed the loose bodies to be composed of osteocartilaginous
