RADIOGRAPHIC ASPECTS OF OSTEOSARCOMA IN MAXILLA: A CASE REPORT

Patient C.B.S, 30 years old, female, with melanoderma, presented as main complaint increased volume in hemiface on the right side. In the extraoral physical examination, facial asymmetry was observed. In the intraoral examination, a lobed exophytic nodule of firm consistency was palpated, sessile base, covered by an integral mucosa of erythematous color, measuring approximately 3 cm. In the panoramic and periapical radiographs, bone spicules and thickening of the periodontal ligament were observed in the mesial of the tooth 16 in all its extension. Computed tomography was requested, which presented multiple exophytic projections with a classic "sunbeam" appearance caused by the excessive production of osteophytic bone in the form of irregularly shaped hyperdense spikes and imprecise limits, which ruptured and expanded the vestibular and lingual cortical bones. The patient underwent incisional biopsy with fragment removal on the right maxillary alveolar ridge. The diagnosis was of chondroblastic osteosarcoma.
