Highlights
Osteosarcoma is the most common malignant bone tumor (Vander Griend, 1996; Marulanda et al, 2008)
The extent of the tumor in both bone and soft tissue is best appreciated with cross sectional imaging techniques such as computerized tomography (CT) or magnetic resonance imaging (MRI)
Pain in the involved region of bone is a unique clinical presentation of osteosarcoma, which is unusual of other tumors and osteosarcoma can be confused with other inflammatory lesions
Summary
Osteosarcoma is the most common malignant bone tumor (Vander Griend, 1996; Marulanda et al, 2008). The most common clinical presentation of osteosarcoma is pain in the involved region of bone, with or without a soft tissue mass. Intraoral examination revealed a well defined swelling along the mandibular arch, extending from the premolar to the retromolar region on left side causing obliteration of the buccal vestibule (Figure 1b). Panoramic radiograph revealed an ill defined, mixed radiolucent-radiopaque lesion along the left body of mandible, denoting irregular areas of osteolysis. The mandibular cross-sectional radiograph showed the Figure 1a: Extraoral photograph: A diffuse swelling over left body and ramus of the mandible. The non-contrast multislice spiral CT scan of the mandible and face revealed expansile destructive complex mass lesion involving the body and ramus of left side of mandible with hypodense to cystic component surrounding it (Figures 2b). The five year survival rate was predicted to be 65.3% (Bielack et al, 2002)
