An odontogenic myxofibroma related to an embedded third molar of the mandible. Report of a case.

A case of odontogenic myxofibroma involving the angle of the mandible is reported. This case arose in the area closely associated with the pericoronal portion of the embedded third molar. When the mandible resected was histopathologically examined, the tumor mass containing various shapes of epithelial cell nests and amorphous calcified bodies in the myxomatous fibrous tissue was found to be formed in the localized area well-demarcated by the enamel of the embedded tooth. These findings strongly suggest that this lesion is of odontogenic origin.
