Odontogenic Myxoma of the Maxilla - A Case Report
Integrative Journal of Medical Sciences, 2019
Introduction : The odontogenic myxoma is a rare benign tumor of the maxilla, whose clinical and radiological manifestations are variable and nonspecific and can be confused with other radiolucent lesions. Its origin would be the embryonic mesenchyme of the dental follicle.Case report : We report the case of odontogenic myxoma of the right maxilla, discovered by chance in a 25 year old patient. Clinically, the patient had painless, firm on palpation, swelling of the right maxilla, impeding chewing and speech. Facial CT-scan showed an expansive osteolytic process blowing the right maxilla off. A biopsy was in favor of an odontogenic myxoma. The diagnosis was based on clinical, radiological and especially anatomopathological arguments.Conclusion : The local aggressiveness of the odontogenic myxoma and its high rate of recurrence justify a radical treatment beyond the lesion’s boundaries and thus imply a postoperative repair.
Management of odontogenic myxoma of the maxilla
Otolaryngology - Head and Neck Surgery, 1997
Myxoma is a relatively rare tumor of mesenchymal origin 1 that can be found in numerous sites throughout the body including the heart, skin, and subcutaneous tissues 'along with various sites in the head and neck. 2 Within bone, a myxoma is most often located centrally in the maxilla and mandible. Odontogenic myxoma is a rare, benign, locally invasive, and nonmetastasizing neoplasm of the jaw bones. The purpose of this article is to review the literature on odontogenic myxoma and to present three cases that were treated at Sunnybrook Health Science Centre with analysis of their management. Special emphasis is placed on the surgical treatment of odontogenic myxoma of the maxilla. CASE RPPORTS Case l. A 15-year-old boy was found by his dentist to have a right palatal lesion. He underwent radiographic investigation, which suggested a cystic lesion involving the maxilla. Biopsy and transoral curettage were performed by an outside oral surgeon. After surgery the patient reported intermittent drainage from an oroantral fistula but had no other symptoms referable to his maxilla. His medical history and review of systems were unremarkable. On examination of his oral cavity, he had an oroantral fistula on the right side. His right maxillary first premolar was mobile without evidence of persistent tumor. The rest of his head and neck examination and general examination was unremarkable. The patient was admitted to the head and neck service at our institution. CT was performed and was noncontributory. A review of the previous pathology confirmed the diagnosis of odontogenic myxoma. He underwent a right partial maxillectomy during which a transoral, sublabial approach with insertion of a maxillary obturator was used. Pathologic analysis revealed replacement fibrosis with scattered peripheral foci of residual myxomatous tumor. He has been followed up for 2 years and has remained disease free. Case 2. A 22-year-old man went to his dentist with a right maxillary mass. He had no other symptoms referable to

Odontogenic myxoma (OM) is a locally aggressive, benign, slowgrowing tumor arising from mesenchyme and/or odontogenic epithelium. It is the third most common odontogenic tumor predominantly affecting females and posterior mandible. Radiographically, OM demonstrates unilocular or multilocular, well or ill-defined radiolucency showing 'honeycomb', 'soap-bubble' or 'tennis-racket' pattern with cortical expansion and tooth displacement. Histologically, OM shows loosely arranged stellate or spindle-shaped cells interspersed in myxoid matrix. Various treatment modalities, such as wide excision, enucleation and curettage, curettage with/without electrical or chemical cautery, enbloc resection and wide resection with/without imme diate grafting can be considered based on the extent of the lesion. Here, we present a case of a 17-year-old female, with OM in the left maxilla and the maxillary sinus.
Odontogenic Myxoma of the Maxilla Infiltrating the Maxillary Sinus: A Rare Case Report
Abstract: Odontogenic myxomas are tumors derived from embryonic mesenchymal elements of dental anlage. Although benign, odontogenic myxomas draw great attention because of their invasive nature into the surrounding tissues, which make the tumour amenable to recur especially after conservative treatment. We present a case of odontogenic myxoma with a displaced maxillary molar in the sinus, an unusual radiographic finding reported in literature.

Odontogenic myxoma: a clinicopathological study of 33 cases
International Journal of Oral and Maxillofacial Surgery, 2004
BACKGROUND: Odontogenic myxoma is a benign, locally aggressive neoplasm of the jaws. Prevalence rates range between 0.5% and 17.7% of odontogenic tumours. There are few reports in the literature on this lesion in African populations, and therefore, this study aimed to report on odontogenic myxoma in a South African population over a 40-year period. METHODS: The clinical records and orthopantomograms of 29 histopathologically diagnosed odontogenic myxoma were retrospectively analysed. Details of age, gender, ethnic origin and clinical, histological as well as radiological features were recorded. RESULTS: The ages of patients ranged from 7 to 44 years with a mean of 21.3 years. The male-to-female ratio was 1:2.6 with the majority of patients being of mixed race and Africans. Clinically, 31% complained of pain while 58.6% had a history of swelling. The majority of odongenic myxomas (62.1%) were located in the mandible with the posterior region being most commonly affected. Multilocular lesions (69.2%) were more common and were significantly larger than unilocular lesions (P < 0.05). The outline of these tumours was mostly well-defined (84.6%) with different degrees of cortication. Only one tumour caused tooth resorption, while 20 cases (76.9%) caused tooth displacement. Six tumours expanded into the maxillary sinus, and 14 tumours caused expansion of the mandible. CONCLUSIONS: Odontogenic myxomas have variable clinical, radiological and histological features. Most of these features in this population were similar to other populations. It is mandatory to use conventional radio-graphs along with histopathological examination to aid in arriving at an accurate diagnosis.
Odontogenic myxoma - A report of two cases
IP innovative publication pvt. ltd, 2019
Odontogenic myxoma is a rare intraosseous neoplasm that has the potential for extensive destruction of the jaws. It is thought to be derived from mesenchymal portion of tooth germ. Odontogenic myxoma mainly affects the mandible, with a peak incidence in the second to fourth decades of life and have predilection for the female sex. In this article, we report two cases of odontogenic myxoma in 31-year-old and 35 year old male patients that involved right maxilla and right mandible respectively.
Maxillary odontogenic myxoma involving the maxillary sinus: case report
Brazilian journal of otorhinolaryngology
The aim of this paper is to report a case of odontogenic myxoma that affected the right maxilla and maxillary sinus. We have also reviewed the literature in regards of the clinical, radiographic, histological and treatment aspects of this pathology. Odontogenic myxomas of the maxillofacial region are benign lesions, without preference for gender, race or location, with extremely varied clinical and radiographic characteristics, thus increasing the number oral and maxillofacial region tumors with which we can make the differential diagnosis.

Odontogenic Myxoma – A Case Report and Clinico-Radiographic Study of Seven Tumors
The Journal of Contemporary Dental Practice, 2006
The primary aim of this paper is to present clinical and radiographic aspects of odontogenic myxomas diagnosed at the Stomatology Clinic of Bauru School of Dentistry, University of São Paulo, Brazil and to compare them with data reported in a series published in the literature. A second objective is to report a clinical case of odontogenic myxoma in a 9-year-old patient in whom the lesion involved the anterior region of the maxilla. Dental records between 1975 and 2000 were reviewed and seven cases diagnosed as odontogenic myxoma were found in individuals aged from nine to 60 years. Of these, four occurred in women and three in men. The mandible was affected in five cases and the maxilla in two. All patients presented with asymptomatic swelling in the affected area. A mixed radiographic result was observed in five patients, while in two patients the lesion was completely radiolucent. The borders of the lesion were well-defined in six patients. In four cases there was dental displace...
