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.
