Abstract
|
|
|
|
Telangiectatic osteosarcoma(TAEOS) is a rare subtype of osteosarcoma(OS) composed of blood-filled or empty cystic architecture simulating aneurysmal bone cyst. TAEOSs account for 2-12% of all OSs. TAEOSs mostly develop around knee and proximal humerus, but TAEOSs of the jaws are rare. To the best of my knowledge, this is the fourth case of primary TAEOS affecting the jaws. A 36-year-old female who had been previously diagnosed osteosarcoma by biopsy reported with a chief complaint of throbbing and swelling of the right mandible. The patient received neoadjuvant chemotherapy followed by hemi-mandibulectomy. After surgery, patient received adjuvant chemotherapy. The patient is free of disease for 6 months after surgery. TAEOSs are mimicking other benign entities, such as aneurysmal bone cyst and central giant cell granuloma. Thus, careful diagnosis through thorough radiographic and histopathologic evaluation is important to establish a treatment plan, prognosis, prediction and management strategy.
