Abstract
Introduction: The odontogenic myxoma is a rare benign tumor of the maxilla, whose clinical and radiological manifestations are variable and nonspecific and can be confused with other radiolucent lesions. Its origin would be the embryonic mesenchyme of the dental follicle.Case report: We report the case of odontogenic myxoma of the right maxilla, discovered by chance in a 25-year-old patient. Clinically, the patient had painless, firm on palpation, swelling of the right maxilla, impeding chewing and speech. A facial CT scan showed an expansive osteolytic process blowing the right maxilla off. A biopsy was in favor of an odontogenic myxoma. The diagnosis was based on clinical, radiological, and especially anatomopathological arguments.Conclusion: The local aggressiveness of the odontogenic myxoma and its high rate of recurrence justify a radical treatment beyond the lesion’s boundaries and thus imply a postoperative repair.

Summary
Myxomas of the maxilla are benign odontogenic tumors of mesodermal origin, with high destructive potential. They occur most often among young adults and only represent 3% of odontogenic tumors, and 0,41% of bone tumors.[1] Clinical and radiological manifestations are variable and can be confused with other benign or malignant lesions of the maxilla.We report the case of a myxoma of the maxilla, with a review of the literature, allowing for a diagnostic and therapeutic difficulty analysis. The extraoral physical examination revealed a facial asymmetry due to a right cheek mass, merged with the maxilla, covered with healthy skin.
