Odontogenic Fibromyxoma of Maxilla: A Rare Case Report

Abstract

Fibromyxoma is a rare odontogenic tumour which is benign, but locally aggressive. The etiology of these tumours is unknown, but because of its limitation to the teeth bearing areas and occasional presence of odontogenic epithelial fragments within the tumour which suggest that it is of odontogenic origin. It is a slow growing painless tumour that frequently occurs in second and third decades of life. Females are more commonly affected than males. The tumour can cause gradual expansion of the cortical plates and cause loosening and displacement of teeth, although root resorption may be rare. The surgical treatment of these tumours consists of complete enucleation or radical excision. The aim of this paper is to present the rarity of a fibromyxoma of the maxilla.

Fibromyxoma of the Jaw: Case Report and Review of the Literature

“…Fibromyxomas express vimentin and are typically negative for S-100, CD34, SMA, and CD68 [19]. A summary of the reported demographics and histopathological characteristics of odontogenic fibromyxomas published within the last 10 years is provided in Table 1 [14,18,[20][21][22][23][24][25][26].…”

An Uncommon Mesenchymal Tumor of Maxilla

“…It accounts for only 1 to 3% of all tumors of the jaws, with an incidence rate of 0.07% new cases per million people per year. 6 Myxomas of jaws may be odontogenic in origin (HmTison, 1973). As bony myxomas almost exclusively occur only in the jaws, it is also suggested that they arise from the mesenchyme of the tooth germ (Pindborg, 1965).…”

Odontogenic myxofibroma- Report of a rare entity

“…This involves enucleation and curettage, radical surgery and en block resection depending on the size of tumor. 8,6 There have been higher recurrence rate for this tumor between 25% and 43%. 8 This recurrence is mostly due to incomplete removal of tumor rather than true recurrence.…”
