case_images: The associated teeth were mobile, and both the lingual and buccal sulci were obliterated by the tumour mass (Figure 1).
case_images: Oblique lateral views of the mandible and posteroanterior view of the jaws for case 1 demonstrating an osteolytic lesion (with centrifugal radiopaque spikes) within which the faint presence of an irregular, shapeless mass of radiopacity can be seen-white arrow.

case_images: The radiographic appearance is as shown in Figure 2.
case_images: (a) Osteoblastic variant of osteogenic sarcoma of case  1 showing osteoblasts with cytonuclear pleomorphism and hyperchromatic nuclei surrounding malignant osteoid (X100). (b) Cemento-osseous dysplasia showing a benign mesenchymal neoplasm composed of irregular islands of immature bone with osteoblastic rimming surrounded by a moderately dense fibrous connective tissue stroma (X100). (c) A possible transition zone between osteogenic sarcoma and cemento-osseous dysplasia (X400). (d) Chondroblastic osteosarcoma of case 2 showing a malignant mesenchymal neoplasm consisting of pleomorphic chondroblast with prominent hyperchromatic nuclei amidst malignant osteoid(X100).

case_images: An incisional biopsy of the right mandibular lesion revealed chondroblastic osteogenic sarcoma (Figure 3(d)).
case_images: An orthopantomogram of the patient in case 2 showing a significant bone destruction of the right mandible extending from the lower right lateral incisor to a region just short of the mandibular angle. The radiolucency also encompasses the irregular mass of radio-opacity just apical to right mandibular first molar. The radiograph shows a similar irregularly shaped radio-opacity within the body of the left mandible.
