The recurrence rate and 95% CI were calculated in relat Recurrence rate ~25% Terminology Odontogenic myxoma Odontogenic myxofibroma Odontogenic fibromyxoma Epidemiology Most cases diagnosed in 2nd - 4th decades but wide age range of occurrence (between 1 to 73 years) More common in women Sites More common in mandible than maxilla 2/3 in mandible Clinical features . Clinically, POM is presented as exophytic slowly growing mass which can be sessile or pedunculated. The papers were evaluated and critically appraised by two independent investigators. Odontogenic myxoma is generally regarded as a rare benign tumor that occurs in tooth-bearing areas of the mandible and maxilla, and is characterized by its slow growth and bony invasions, resulting in painless facial deformity. OM can be central (COM) or peripheral (POM) with the latter being rare and less aggressive. A myxoma is an uncommon connective tissue tumour consisting of scattered stellate cells spread in connective tissue mucin. 1. They are usually not painful. There is a network of reticulin fibres in this expanse of mucin. Context.Odontogenic myxoma is an uncommon tumor that has the potential for extensive destruction of the jaws.Objective.To document the clinical, pathologic, and behavioral features of odontogenic myxomas.Design.Histologic and immunocytochemical examinations were performed on odontogenic myxomas from 25 Chinese patients. Odontogenic myxoma is considered a mesenchymal local aggressive, slow-growing, odontogenic tumour with well-defined pathologic characteristics and may be associated with tooth germ. OM is an odontogenic mesenchymal neoplasm. Although enucleation and curettage have proven effective, the risk of recurrence remains considerable and long-term follow-up is indispensable. Odontogenic myxomas are benign but locally aggressive neoplasms found almost exclusively in the jaws and arise only occasionally in other bones. We review the literature on the features, differential diagnosis, and treatment modalities of this lesion. It preferably locates in posterior mandibular regions, followed by the incisors, maxillary and; exceptionally, the mandibular condyle. Radiographic features Our aim was to establish the recurrence rate of odontogenic myxoma after different treatments. The papers were evaluated and critically appraised by two independent investigators. Specialists *. Abstract. Introduction Last revised by Dr Yuranga Weerakkody . 2. Odontogenic myxoma is a slow growing benign, locally malignant tumour, notorious for recurrence. Symptoms Onset *. [2] Contents 1 Signs and symptoms 2 Diagnosis 3 Treatment Clinically, it is a slow-growing, expansile, painless, non-metastasizing, central tumor of jaws, chiefly the mandible. Local recurrence can is possible. The rate of recurrence decreased from 24.0% to 8.3% when follow-up exceeded 60 months. Odontogenic myxoma (OM) is a rare neoplasm, which originates from odontogenic ectomesenchyme. Odontogenic myxoma can be found most often in young adults aged 25-35 years although lesions may occur over a lifetime, reporting the lowest . Our search covered papers from 1972-2017 from different sources. Cause *. [1] As a myxoma, this tumor consists mainly of spindle shaped cells and scattered collagen fibers distributed through a loose, mucoid material. Odontogenic myxoma represents less than 10% of all odontogenic tumours [ 8, 9 ]. What Information Does GARD Have For This Disease? Although surgery is usually the choice treatment, there is still some controversy concerning surgical techniques and proper indications. Clinical and available follow-up data were analyzed . Odontogenic myxoma is a rare intraosseous neoplasm, which is benign but locally aggressive. Although peripheral odontogenic myxoma is a rare tumor, recent case reports are increasing. We present a classical case of. It originates from the mesenchymal portion of the tooth germ. Though it has slight histologic overlap with other entities, definitive diagnosis is imperative considering the tumor's aggressive nature, high recurrence rate, and necessity of radical surgical intervention in large-sized lesions. Currently GARD is able to provide the following information for this disease: Population Estimate *. Odontogenic myxomas are categorized by the modified WHO classification under odontogenic ectomesenchyme with or without included odontogenic epithelium. Odontogenic myxoma Definition: Odontogenic myxoma is a rare, benign intraosseous tumor. Odontogenic myxoma (OM) is a benign, but infiltrative tumor with mesenchymal cell origin. Odontogenic myxoma is a benign but invasive tumor that has a high rate of recurrence after surgical removal ( Speight, 2013 ). Odontogenic myxoma (OM) is an uncommon benign odontogenic tumor arising from the jaw bone. There is no study in the literature that analyses the best standards for OM diagnosis and how the treatment modalities may influence the recurrence rates. More evidence of long-term outcomes after conservative surgery for OM is needed. Many rare diseases have limited information. It is the third most common odontogenic tumor and accounts for approximately 3%-6% of all odontogenic tumors. The recurrence rate and 95% CI were calculated in relation to each specific treatment, and the chi . Odontogenic myxoma (OM) is a benign intraosseous tumor, but locally invasive, having a high rate of recurrence. It is non-encapsulated, arises from odontogenic ectomesenchyme, develops solely in the jaws, and represent a small percentage of odontogenic tumor overall. Treatment 1..Radical surgery -Should be carried out in the hope of preventing recurrence . Our aim was to establish the recurrence rate of odontogenic myxoma after different treatments. 1,2 OM is frequently reported to be the fourth or third most frequent odontogenic . It is characterized by excessive amount of mucoid ground substance. Genetic Testing *. Odontogenic myxoma. Clinical, radiological, and histopathological features should be considered when making a diagnosis. Epidemiology Typically seen in the 2nd to 3rd decades of life (slightly earlier than ameloblastomas). Odontogenic myxomas are rare tumours that involve the mandible or maxilla and account for 3-6% of odontogenic tumours 2. Our search covered papers from 1972-2017 from different sources. It is considered to be derived from the mesenchymal portion of the tooth germ. Odontogenic myxoma (OM) is a benign neoplasm of ectomesenchymal origin with aggressive, potentially infiltrative, behaviour and is further defined as "an intraosseous neoplasm characterized by stellate and spindle-shaped cells embedded in an abundant myxoid or mucoid extracellular matrix". Odontogenic myxoma (OM) is an uncommon benign odontogenic tumor arising in the jaw. odontogenic myxoma is an uncommon benign odontogenic tumour that derives from mesenchyme, or odontogenic ectomesenchyme, or both, with or without epithelium.1 it comprises 0.5% of all bony tumours and 3%-6% of odontogenic tumours. Odontogenic myxoma is an uncommon benign tumor that mainly affects the mandible, with a peak incidence in the second to fourth decades of life and predilection for the female sex. We describe the case of a 13-year-old boy who developed recurrence of an odontogenic myxoma of the mandible. Abstract. Odontogenic myxomas are rare tumors that involve the mandible or maxilla and account for 3-6% of odontogenic tumors 2. The odontogenic myxoma is an uncommon benign odontogenic tumor arising from embryonic connective tissue associated with tooth formation. The diagnosis poses a challenge because its clinical features overlap with those of other benign and malignant neoplasms. Symptoms *. Objective It rarely occurs in any bone other than jaws and peripherally. The greater variability in the clinical and radiological features of odontogenic myxoma emphasizes that it should be considered in differential diagnosis of both radiolucent and radiopaque lesions in both jaws. Introduction. 2 according to some studies it is the second most-common benign odontogenic tumour, 3 is commonly seen in the Pathology Arises from mesenchymal odontogenic tissue. These lesions share clinical and histopathological features with many odontogenic tumors . . Odontogenic myxoma is a benign but locally aggressive intraosseous lesion of the jaws. We present a rare case of odontogenic myxoma occurring in the mandible of a 19-year-old male patient with a brief review of clinical and radiological features, and diagnostic and operative . It rarely appears in any bone other than the jaws. Epidemiology Typically seen in the 2 nd to 3 rd decades of life (slightly earlier than ameloblastomas). Its radiological appearance is of a "soap bubble" or "tennis racquet strings" [ 24 ]. Abstract.
