Abstract
- Fibromyxomatous lesions of the maxilla are rare. Although other locations are also uncommon, this tumor can occasionally be found in jawbone. They are slow-growing, which result in expansion of the surrounding bony cortices. Maxillary and man-dibular myxomas are locally aggressive neoplasms that are thought to arise from fibroblasts of the dental papilla or sinonasal mucosa. The precise origin of these tumors, however, remains controversial. When present in the maxilla, they can extend into the maxillary sinus, the nose, or the orbit. The differential diagnosis should be made from neoplasms in which myxomatous change can be a prominent secondary feature such as liposarcomas, chondrosarcomas, and neurofibromas. We report a case with a large maxillary mass occluding the nasal cavity and expanding hard palate and gingivobuccal area. The histopathologic diagnosis was odontogenic fibromyxoma originating from canine tooth. The treatment was medial maxillectomy.
