title: Maxillary osteosarcoma masquerading as chondromyxoid fibroma: report of a case.
abstract: Osteosarcomas are highly malignant bone tumours. Its appearance in craniofacial bones is a rare entity and accounts for only 1% of all head and neck malignancies. We present an uncommon case report of a 42 year old male patient with osteosarcoma of left maxilla, which was successfully excised under general anesthesia. The patient reported to us with a history of pain, swelling, pus discharge and tooth extraction, which led to the differential diagnosis of suppurative osteomyelitis, dentoalveolar abscess, benign odontogenic tumour, an infected cyst etc. Histopathological examination of incisional biopsy was reported as chondromyxoid fibroma which is a rare benign tumour. However the excisional biopsy specimen was reported as osteosarcoma of maxilla. The clinical presentation, diagnostic challenges and its therapeutic approach are addressed. This case serves to emphasize the need to recognize osteosarcoma when it presents in unexpected locations, especially because of its rarity.
