[Odontogenic myxoma of the maxilla: report of a case].

Myxoma is a rare variety of benign tumors of the jaw, whose origin is embryonic mesenchymal dental follicle. Clinical and radiological manifestations are variable and non-specific and can lend confusion with other lesions. We describe a case of very invasive odontogenic myxoma , observed in a woman of 51 years. Clinically, the patient had left maxillary swelling, painless, firm to the touch. CT facial bones showed an expansive osteolytic process blowing the jaw. The treatment consisted of a wide excision of the tumor by endobuccal way, the tumor is individualized well from the bone. Pathological examination of the surgical specimen was diagnosed odontogenic myxoma. The short-term trend has shown no clinical and radiological local recurrence. The diagnosis is based on clinical, radiological and histological. This tumor is locally aggressive, which can lead to significant facial deformities and dental disturbances. The recurrent nature of myxoma imposes a broad radical treatment beyond the limits of the lesion. The loss of important substance required surgical repair or prosthetic.
