Osteosarcoma of mandible: Detailed radiographic assessment of a case

Abstract

Osteosarcoma (OS) is a malignant connective tissue tumor originating from bone and is the most common primary bone malignancy of long bones but seldom arises in jaw bones. Osteosarcoma of jaws is frequently seen arising in the second and third decade as compared to earlier occurrences in other bones and show a slight predilection for body of mandible. It is a highly malignant tumor with varied radiographic features. We present a case with detailed radiographic assessment using intraoral radiograph, computed tomography (CT), 3-D CT, CT angiography techniques and histological evaluation.

Osteochondroma of condyle: case discussion and review of treatment modalities

“…A homogenous new cortex without lamellae formation is indicative of benign process while osteosarcoma shows perpendicular radiating spicules of dysplastic osteoid. Symmetric widening of periodontal ligament space is seen in osteosarcoma arising in tooth-bearing regions 11. Clinical features and detailed history regarding symptoms and rate of growth of tumour may provide a clue to differentiate benign and malignant tumours but a representative surgical specimen should be obtained to rule out malignancy and arrive at definitive diagnosis.…”

Lumps and Bumps of the Gingiva: A Pathological Miscellany

“…The presentation of head and neck osteosarcoma depends on the location of the tumor, with most patients presenting with a mass alongside pain, possible paresthesia and loosening of teeth [ 31 , 50 ]. Radiographically, an ill-defined mixed radiolucent and radiopaque lesion is seen, occasionally with the classical “sunburst” appearance [ 52 ]. Chondrosarcoma shows a similar clinical picture, with swelling being the primary presentation and other symptoms are specific to the location of the tumor, such as cranial nerve dysfunction, loose teeth and pain [ 31 , 51 ].…”

“…Based on the radiology, the clinical differential for an osteosarcoma may include osteomyelitis [ 52 ], and in some cases without significant bony destruction, the possibility of a benign cemento-osseous lesion may be raised [ 53 ]. The clinical differential for a chondrosarcoma may include osteosarcoma or another more common malignant tumor such as a squamous cell carcinoma [ 22 ].…”

Osteosarcoma of the maxilla: A case report and review of literature

“…Lymph nodes are rarely involved in this tumor. [5] CASE REPORT This is a case of 61-year-old male, chronic smoker and diabetic, who came with progressively increasing swelling over left nostril and cheek with intermittent bleeding from nostril for about 7 months [ Figure 1]. He had difficulty in breathing with stuffy nose on the left side.…”
