Odontogenic myxoma with radiographic aspects in sunlight.

Introduction: Odontogenic Myxomas are found mainly in young adults with a mean age between 25 and 30 years, but they can occur in a wide age range without gender predilection. The mandible is more commonly affected than the maxilla, and minor lesions may be asymptomatic. This work aims to report a clinical case of Odontogenic Myxoma with radiographic aspects in sunlight. Case Report: A 21-year-old female patient sought a diagnostic service reporting an increase in volume in the left hemiface for five months. On extraoral clinical examination, it was possible to notice an increased volume in the left hemimandible of firm consistency on palpation. On intraoral examination, he had a vestibular bulge with intact overlying mucosa. The imaging exams were ordered for diagnostic purposes. Cone-beam computed tomography revealed a well-delimited, multilocular hypodense image extending from the premolars to the mandibular notch. It was possible to notice the presence of periosteal reaction in the buccal bone plate with aspects of sun rays. Because of the radiographic characteristics, the diagnostic hypotheses were osteosarcoma and Odontogenic Myxoma. Conclusions: The patient underwent hemimandibulectomy, and the surgical specimen was sent for analysis. In the histological examination was observed fusiform and stellate cells arranged in a loose myxomatous connective tissue. The final diagnosis was Odontogenic Myxoma. After one year of treatment, no signs of lesion recurrence were observed. [ABSTRACT FROM AUTHOR]
