Background: Myxoma is a rare benign odontogenic tumour affecting the maxillomandibular bone bases. Its incidence is variable, ranging from 0.04% to 2.3%. We report a case of odontogenic myxoma in a 46-year-old patient treated at the odontostomatology department of the Idrissa Pouye General Hospital in Dakar.

Clinical Observation: This was a 46-year-old patient referred for a lower genial swelling that had been developing for more than two years and had caused aesthetic damage and functional impairment. The exobuccal examination showed facial asymmetry without satellite adenopathy. The intraoral examination, apart from poor oral hygiene, revealed a tumour mass located on the right mandibular crest, filling the vestibule extending from tooth 45 to the retromolar trigone. The covering mucosa appeared healthy with some inflammatory areas retaining the imprint of the antagonist teeth. On palpation, the tumour was painless, firm, mobile and bleeding on contact with a wide sessile base, imaging noted an osteolytic image with clear limits blowing the bony cortex without invasion of the soft parts. The management carried out under general anesthesia consisted of surgical excision. The histopathological examination concluded in an odontogenic myxoma. Periodic checks were carried out with good postoperative outcomes. No recurrence was observed 1 years after the intervention.

Conclusion: Myxoma is a benign tumour affecting the maxillomandibular bone bases, the management of which consists of surgical excision. Regular monitoring and control is essential postoperatively due to the possibility of recurrence.
