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.
Odontogenic Myxoma in the Maxilla
Journal of Gandhara Medical and Dental Science
SUMMARYThe aim of this paper is to determine the unique and very interesting case of odontogenic myxoma, which involved the right maxilla and its sinus. Odontogenic myxomas are considered to be a benign odontogenic tumor with locally aggressive behavior and non-metastasizing neoplasm of the jaw bones. It represents an uncommon benign neoplasm comprising 3–6% of all odontogenic tumors. It is usually derived from the dental mesenchyme or periodontal ligament. Despite the benign nature of myxoma, there is a high rate of local recurrence after curettage alone and thus in certain cases adequate resection is the only option.
Odontogenic myxoma in the maxilla: A case report and characteristics on CT and MR
Oral Oncology Extra, 2006
The findings of a computed tomography (CT) and magnetic resonance (MR) are reported in this study for a odontogenic myxoma arising in the maxilla of a 22 years-old Brazilian woman. The CT showed an expansive formation of circular aspect located in the alveolar process of the left maxilla with slight heterogeneous distinction after iodinized contrast. Unilateral crowding with displacement of some dental elements inside the lesion was shown in the MR and CT images. The MR images showed a well-defined and smooth-walled mass lesion with low signal intensity on T1-weighted images and high-signal intensity on T2-weighted images. The treatment of choice was a surgical tumoral resection and three applications of cryotherapheutic agent for 1 min in the same surgical time with interval of 5 min between them.

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 - 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.
Odontogenic Myxoma. A case report
Myxomas of the jaws are rare odontogenic neoplasm predominantly found in young adults. It commonly occurs in the second and third decade, and the mandible is involved more commonly than the maxilla. It constitute around 3-6% of total odontogenic tumours and most of the times it grows without symptoms and presents as a painless swelling. Here we are presenting a case of odontogenic myxomas (OM) of 22 yr. old patient in upper left maxillary region.
Infiltrative odontogenic myxoma of the posterior maxilla: Report of a case
Journal of Natural Science, Biology and Medicine, 2013
Myxomas of the head and neck are rare tumors of uncertain histogenesis. Odontogenic myxomas in maxilla are less common but behave more aggressively, as it spreads through maxillary antrum. It therefore reaches considerable size before being detected. The current case arouses particular interest due to the rapid growth and infiltrating nature of the lesion in a 25-year-old female patient, who denied any leading symptoms, even with the lesion involving extensively. Radiographic and microscopic similarities to a number of entities make diagnostic interpretation of odontogenic myxoma challenging. Therefore sound knowledge of clinical, radiographic and histopathologic features is important to establish an appropriate treatment aimed at a good clinical course and patient cure.
Odontogenic myxoma: Report of a case with peculiar features

Myxoma is a relatively rare tumor mainly found in the left atrium of the heart or centrally in bone. Occasionally, myxoma is found in other sites, such as skin, larynx, and subcutaneous tissue.1'3 The most common location in bone is centrally in the maxilla or mandible, with a slight preference for the mandible.4 The jaw myxoma, an uncommon lesion,3*5-8 rarely occurs before age 10 or after 50 years of age 6.7.9-14 and shows no apparent sex preference. 7.10-12 The tumor is asymptomatic, with slow, progressive, insiduous swelling as the predominant symptom.6~8~"~14~19 Other findings are loosening of teeth, malocclusion, root resorption, and only rarely paresthesia, hyposensibility, anesthesia, or negative vitality on pulp testis of teeth in the affected quadrant.6 Radiographically, the tumor is usually a radiolucent, multilocular lesion with poorly defined margins, often demonstrating fine soap-bubble or honeycombed trabeculations in the central area.*' Occasionally, a well-defined sclerotic margin is scalloped between the teeth." The roots of the teeth may show resorption. Myxoma occasionally may also appear as a unilocular lesion and behave less destructively than the larger, multilocular variety.'* The tumor must be considered benign, although it is locally invasive6,'4*23 and has a high rate of recurrence.1~10~1'3'3.24~26 Appropriate treatment for odontogenic myxoma is conservative surgery; extensive
