A case report of conventional chondrosarcoma of mandible

A 19 year old female patient presented with chondrosarcoma in left mandibular region near angle of mouth. The commonest sub type of chondrosarcoma is Conventional Chondrosarcoma which may be low, intermediate or high grade. They are frequently seen in the 4th and 5th decades with a slight male predominance 1.5–2.0:1. They can also be classified on their location within bone into Central, Peripheral, and Juxtacortical Chondrosarcomas. Rare subtypes of chondrosarcoma like Dedifferentiated, Mesenchymal and Clear Cell Chondrosarcoma are also seen. The extent of the tumour within the bone and extension into soft tissue can be delineated by MRI preoperatively. Being radioresistant, it is usually surgically treated by wide resection. Prognosis of jaw lesions is poor as compared to the lesions affecting the long bones of the body. Death occurs usually by direct extension to the base of the skull or due to distant metastasis to lungs and otherbones.
