Primary juxtacortical chondrosarcoma of mandibular symphysis: Unique and rare case report.

Juxtacortical chondrosarcoma (JC) is a rare, malignant, cartilage-forming tumor arising from the external bone surface. It mainly involves long bones and very rarely involves maxillofacial skeleton. Chondrosarcoma in general accounts for about 10-20% of all bone neoplasm, of which only 1-3% is involved in maxillofacial skeleton. So far only two cases of JC have been reported in mandible. In this article we report a rare case of JC in a 49-year-old male primarily involving symphysis of mandible. This is the third case of JC in mandible and first of its kind to be reported in mandibular symphysis region is concerned. Literature relevant to its clinical, radiological features, and prognosis is analyzed.
