    Abstract:
    OBJECTIVE: Odontogenic myxoma is an uncommon tumor that represent less than 0,5% of all bone tumors and only 3 to 6% of odontogenic tumors. The aim of this article was to catalogue the clinical cases diagnosed microscopically as odontogenic myxoma and to describe their clinical and radiographic characteristics, comparing these to the data found in the current literature. DESIGN: Histological and immunocytochemical examinations were performed on odontogenic myxomas from four Tunisian patients in a period of 23 years. RESULTS: In the present series, two were male and two female. The age at diagnosis ranged from 19 to 38 years. Three tumors involved the mandible and one occurred in the maxilla. In all cases with radiographic records, lesions presented with a multilocular and osteolytic appearance. Histologically, odontogenic myxomas were mainly composed of spindled or stellate-shaped cells in a mucoid-rich intercellular and alcian blue positive matrix. All cases were treated by tumor-enucleation. There was no evidence of recurrence after 2 to 8 years. CONCLUSION: Clinical and radiological aspects of odontogenic myxomas are not conclusive; a histopathological examination of the lesion is mandatory in order to make the right diagnosis. Because of its high rate of recurrence, surgical treatment through bone resection is the most indicated treatment modality, and the patient must be followed-up closely for years.
