Odontogenic myxoma is a comparatively rare lesion of the jaw bone. A case of odontogenic myxomaoccurring in the mandible of a young girl that was treated by two-stage surgery to preserve the form of themandible is presented. A 12-year-old girl was referred to our hospital because of a painless swelling in the rightlower molar region. Radiographic examinations revealed multilocular radiolucency with a fine“soap bubble”appearance, accompanied by impacted second and third molars, at presentation.<br> As much as possible of the tumor was removed by an intraoral approach with the patient under general anesthesia. To conserve jaw and mouth function, segmental resection was not performed. Histological examination revealed a tumor consisting of proliferative spindle cells without nuclear atypia in an abundant myxoid stroma. Islands of odontogenic epithelium were found within the tumor. A pathologic diagnosis of odontogenic myxoma was made. Three years later, secondary surgical removal of the tumor was carried out after the bone had regenerated. At present, 3 years after secondary surgery, bone has formed in the cavity remaining after the operation, and the tumor has not recurred. The patient will be carefully observed for tumor recurrence hereafter.
