Introduction
Aggressively proliferating intraoral mass with extraoral facial swelling clinically points towards malignant pathology which needs urgent intervention, but at times so called diagnostic ‘gold standard’ histopathology can differ from actual pathology due to poorly representative biopsy site.
Some pathologies show higher risk of such misdiagnosis. Comprising of only 5-8% of jaw tumours1, Chondroblastic osteosarcoma is being one of the such pathologies with many clusters of representative tissues. It generally consists of variants like osteoblastic, chondroblastic and fibrous,2 small cell3 but single pathology can have areas dominant in proliferating chondroblasts, or hyalinized areas with proliferating fibroblasts or myxoid and osteoid areas each prone to be confused with separate pathologies. As site of biopsy governs the final diagnosis and management protocol, maxillofacial surgeons should be attentive to the delusional manifestations of Chondrogenic Osteosarcoma and have a high index of suspicion to start prompt treatment to increase chances of a favourable outcome.
