Central chondrosarcoma of a pediatric mandibular condyle: A case report and review

Chondrosarcoma of mandibular condyle is an extremely rare clinical entity with only 18 cases reported till date. We report a rare case of central myxoid chondrosarcoma in a 7 year old male child with a complaint of slow growing bony hard swelling of left mandibular condyle. Panoramic radiography and CT scan revealed a 5×3cm osteosclerotic and osteolytic lesion with cortical perforation on the medial side of the left mandibular condyle with a cortical expansion of lateral side. Segmental mandibulectomy with disarticulation of the left condyle was done. To the best of our knowledge it is the first case of chondrosarcoma of the paediatric mandibular condyle to be reported. The etiopathogenesis, clinical, radiological diagnosis and various treatment modalities of chondrosarcoma are discussed.
