[Odontogenic myxoma of the ascending mandibular ramus. Bibliographic review and report of a clinical case].

A case of odontogenic myxoma is reported within a review of the literature. It is suggested that the lesion is of odontogenic origin, also that the precursor cell should be called myxoblastoma . The fact that the myxoma could perforate the cortex and invade the soft tissue is very important for the prognosis and treatment , because it is known that, if a myxoma is originated in the soft tissue, it will be less aggressive. It should be asked for a special stains, within the histopathologic diagnosis, because they are used to differ between this tumor, from the so called "myxomatous degeneration". Speaking of the treatment, a Steinmann nail bent like a 7, was used after the resection, to avoid the facial deformity, keeping in a such a way, the working function.
