mor, incidence rate is approximately 0.07 new cases per million people per year [7,8].All reports generally agree that the tumour frequently presents in the second or third decades of life [8][9][10].Most common clinical characteristics of odontogenic myxoma are swelling of the jaws with only few patients complaining of pain, paraesthesia and ulceration, 28% for pain and 56% for swelling [11].Several studies indicating that there is a higher rate of tumour incidence in the mandible than the maxilla [12][13][14][15], and almost occurring in the premolar and molar region of both jaws and rarely crosses the midline [12,16,17].Cortical expansion and perforation are common findings; however, maxillary myxomas often extend into the sinus [18].

This article presents a rare case of odontogenic myxoma occurring in the maxilla of a 42-year-old female patient with review of the literature emphasizing a huge controversy regarding the surgical management.

88Miksoma, nispeten az sıklıkta görülen bir tümör olup genellikle erişkinlerde ve kardiyak yerleşimli olarak izlenir. Pediatrik grupta ve fasiyal kemiklerde görülmesi oldukça nadirdir. Tümörün lokal agresif bir karakteri vardır. Genellikle yavaş ilerleyen bir kitle şeklinde ortaya çıkar ve fasiyal kemiklerde lokalize olursa bu bölgenin diğer yer kaplayan lezyonlarıyla karışabilir. Görüntüleme bulguları spesifi k olmadığından kesin tanı genellikle histopatolojik olarak konur. Tümörün nüksetme potansiyeli nedeniyle agresif rezeksiyonun yanı sıra enükleasyon ve yakın takip tedavi seçenekleri arasındadır. Tedavi şekline etki eden faktörler hastanın yaşı, tümörün yerleşimi, büyüklüğü, daha önce nüks etmiş olması ve hayati organlara yakınlığı şeklinde sayılabilir. Bu bildiride tanısal amaçlı elde edilen radyolojik görüntüleme bulguları ve tanıya faydaları tanımlanmış ve ayırıcı tanıda yer alan lezyonlar tartışılmıştır.Anahtar Kelimeler: Miksoma,bilgisayarlı tomografi ,manyetik rezonans görüntüleme, pediatrik Myxoma is a relatively rare benign tumour found mainly in the adult population which tends to be located in left atrium. Pediatric age and facial bone involvement are very infrequent. Myxomas are locally aggresive, expansile tumors with a slow growing pattern. Other space occupying lesions of the maxillofacial region may cause diagnostic diffi culty since the imaging fi ndings are not spesifi c. Consequently histopathological evaluation is required for the fi nal diagnosis. On the basis of locally recurrent potential of the lesion, aggresive wide resection is usually the choice of surgical treatment. Enucleation and curretage with short-interval follow-up is also suggested. Patient's age, lesion location and dimentions, history of recurrence and relation with the neighboring anatomical structures are the indicators to choose the type of treatment. Herein, imaging fi ndings of a pediatric mandibular myxoma are described and radiological diff erential diagnosis is discussed.

“…1,2 Although little is known about the histogenesis of this neoplasm, it is believed to arise from odontogenic ectomesenchyme, since it bears close microscopic resemblance to the mesenchymal portion of a developing tooth, a portion from which the dental pulp also develops. 2 Dental pulp stem cells could therefore be considered candidate OM precursor cells.…”

Dental pulp stem cells express proteins involved in the local invasiveness of odontogenic myxoma

Little is known about the histogenesis of the odontogenic myxoma (OM). Dental pulp stem cells could be candidate precursors of OM because both OM and the dental pulp share the same embryological origin: the dental papilla. For the purpose of comparing OM and stem cells, this study analyzed the expression of two proteins related to OM invasiveness (MMP-2 and hyaluronic acid) in human immature dental pulp stem cells (hIDPSCs). Three lineages of hIDPSCs from deciduous and permanent teeth were used in this study. Immunofluorescence revealed positive reactions for MMP-2 and hyaluronic acid (HA) in all hIDPSCs. MMP-2 appeared as dots throughout the cytoplasm, whereas HA appeared either as diffuse and irregular dots or as short fibrils throughout the cytoplasm and outside the cell bodies. The gene expression profile of each cell lineage was evaluated using RT-PCR analysis, and HA was expressed more intensively than MMP-2. HA expression was similar among the three hIDPSCs lineages, whereas MMP-2 expression was higher in DL-1 than in the other cell lines. The expression of proteins related to OM invasiveness in hIDPSCs could indicate that OM originates from dental pulp stem cells.
