Odontogenic fibromyxoma of the maxilla: a case report and review of the literature

Eva-Maria Dietrich et al. Case Rep Med. 2011.

Abstract

Fibromyxoma represents a rare benign neoplasm that mostly affects the posterior region of the mandible. Here, we report the case of a 46-year-old male with a swelling of the right maxilla. After proper diagnosis, he was treated with enucleation and curettage of the tumor. The defect was filled with a pedicled buccal fat pad flap. The mesenchymal origin from the dental follicle of the fibromyxoma is the most plausible explanation. Radiological examination with MRI, CT, and conventional radiography contributes to the differential diagnosis from other benign tumors, such as the ameloblastoma. Its management is surgical and comprises enucleation and curettage or en bloc resection. Patients must be monitored for at least two years postoperatively in order to diagnose possible recurrence. According to the literature, the maxilla is a rare location of a fibromyxoma and, to our knowledge, our case is the 30th presented case of a fibromyxoma of the maxilla.

Histopathological examination revealed that randomly stellate, oval or spindle-shaped cells in a myxoid stroma, septa of residual lamellar bone and odontogenic myxoma are present into the marrow space in a pseudomalignant pattern. Variable amount of collagen fibres can be seen (x200, H + E).
