MIRANDA TARRAGO, Josefa Dolores et al. Odontogenic myxoma, a challenge to diagnosis. Rev Cubana Estomatol [online]. 2008, vol.45, n.3-4. ISSN 0034-7507.

The case of a 41-year-old male white patient who smokes and drinks alcoholic beverages and that on the physical examination manifests a rosette-like tumoral lesion of 3.3 cm of diameter that ocuppies the edentulous area of the inferior right alveolar crest of the mandible corresponding to the first and second molars is presented. In the panoramic radiography, it was observed a radiolucid multiocular area that respects the border of the mandible with an irregular cortical in some areas. An odontogenic myxoma was histopathologically diagnosed by using hematoxylin and eosin staining. The patient was surgically treated and the diagnosis was confirmed by alcian blue staining, which yielded positive. As the odontogenic myxoma is a tumor with neither clinical nor pathognomic radiographic characteristics, inaccurate symptoms, local aggresive behavior and frequent relapses, it should always be taken into account in the differential diagnoses of the tumors of the maxilla and the mandible.
