LAZO- VALLADARES, Ángel  e  ALFARO- ALCOCER, Eduardo. Carcinoma mucoepidermoide central de la mandíbula, en un paciente con displasia fibrosa quística mandibular. Acta méd. costarric [online]. 2006, vol.48, n.4, pp.212-214. ISSN 0001-6002.

Mucoepidermoid carcinomas of the salivary glands are frequent lesions that account for 15% of all salivary gland tumors, they are very infrequent in the mandible, with less than 200 cases reported and known as central mucoepidermoide carcinoma. The pathogenesis of this intraosseous tumor is still controversial. Several theories of their pathogenesis have been postulated: 1) entrapment of retromolar mucous glands within the mandible, 2) maxilla sinusepithelium, 3) iatrogenic entrapment of minor salivary glands (chronic osteomielitis or sinusitis, 4) dental lamina remnants, 5) developmentally included embryonic remnants of submandibular glands within the mandible, 6) neoplastic transformation of mucus-secreting cells in the epithelial lining of odontogenic cysts. We present the case of man with a central mucoepidermoide carcinoma and review of the literature of this uncommon condition.
