CHONDROBLSTOMA ON TEMPOROMANDIBULAR JOINT, A CASE REPORT
Abstract
- Chondroblastoma is a rare primary bone tumor which originates from cartilage, and represents approximate 1% af all bone tumor. The chondroblastoma arises most frequently from the epiphysis of the long bones with the humerus being the commonest site. It afflicts usually the young under 25 years with greater incidence in male. As there is no cartilage cell on craniofacial bone which is mainly fromed by intramembranous ossification, the chondroblastoma on the craniofacial bone is extremely rare. But the chondroblastoma recurred frequently in craniofacial bone when the mass is excised incompletely or curretted and, as the tumor has the outstanding ability of local invasiveness, it destructs the adjacent bone. In addition, it is difficult to diagnose differentially from sarcoma or giant cell tumor histopathologically. Due to the entities described above, it is necessary to remove the entire tumor mass as complete as possible, to treat with radiation pre or postoperatively for preventing from recurrence, and to observe for a long time. The chondroblastoma on temporal bone is rare and is difficult to diagnose and treat successfully. So we'd like to present a case of chondroblastoma which was originated from temporal side of TMJ with literatural review.
