Odontogenic myxoma in the maxilla: clinical case report

Resumo

Odontogenic myxoma is a rare, benign tumour of ectomesenchymal origin, characterised by locally invasive behaviour, with treatment directly related to recurrence. This neoplasm is uncommon and grows slowly. Despite its benign nature, its characteristics can lead to facial deformities and significantly impact patients’ quality of life. Objective: This study reports a case of odontogenic myxoma in the maxilla of a 15-year-old male. Case report: The patient who attended a stomatology clinic complaining of asymptomatic swelling of the left cheek. On clinical examination, an increased volume was observed below the left orbit, along with orbital asymmetry and an intraoral tumour. Complementary exams, including radiography, tomography, vitality testing, and needle aspiration, suggested odontogenic myxoma, later confirmed by incisional biopsy and histopathological examination. The patient was referred for surgical resection and remains recurrence-free after 20 months, having completed rehabilitation. Discussion: This case highlights the importance of precise diagnosis and an individualised treatment plan to optimise prognosis and improve patients’ quality of life. Conclusion: Odontogenic myxoma requires careful diagnostic and therapeutic approaches due to its locally invasive behaviour and potential impact on patients’ function and aesthetics.
