A. Complete obliteration of the right maxillary sinus by the tumor mass. B. Extensive involvement of the lateral wall of the nose. OM cases at age of 3 months to 19 months have been reported in the literature. 4,9 A 75% of OM cases are detected between 2 nd and 4 th decade of life, with mean age of 30 years. 2,6 It is believed that only 7% of cases occur in patients aged less than 10 years. 10 Our case has been diagnosed at the age of 11, however the lesion must have started much early in the patient's life. On an average, the age of diagnosis of OM is around 1-5 years delayed from the onset of the lesion. 9 Exceptionally, OM can grow rapidly and that seem to occur in very young

Odontogenic Myxoma is a relatively rare neoplasm which is almost exclusively seen in tooth bearing areas. They constitute around 3-6% of total odontogenic tumours. Odontogenic Myxoma occurs commonly in mandible and their presentation in maxilla is rare. Here we report one such rare case of odontogenic myxoma occurring in the maxilla of an 11-year-o...

Odontogenic myxoma (OM) is a mesenchymal tissue benign neoplasia, being relatively rare which is almost exclusively seen in tooth-bearing areas. OM commonly occurs in the 2(nd) and 3(rd) decade and the mandible is involved more commonly than the maxilla. The lesion often grows without symptoms and presents as a painless swelling. Radiographically,...
Abstract: This is a case report of an Odontogenic myxofibroma in a paediatric patient. This lesion, also called odonto- genic myxoma, is an uncommon benign odontogenic tumour that derives from mesenchymal elements. Odontogenic myxofibroma in paediatric age is rare, because is more frequently discovered between the second and the fourth decade. Clin...

... It arises from odontogenic ectomesenchyme, i.e., dental follicle, dental papilla, and periodontal ligament. [1,2] In 1992, the WHO defined OM as a locally invasive neoplasm consisting of rounded and angular cells lying in an abundant mucoid stroma. It is a painless slow-growing tumor commonly occurring in the mandible and has less tendency to metastasis. ...
... [1,2] Two forms of myxomas have been identified those derived from "facial bones" and they are either osteogenic myxoma or odontogenic myxoma (OM) and another derived "soft tissue" like perioral soft tissue, parotid gland, ear or larynx. [2,3] OM represents an uncommon benign neoplasm comprising of 3-6% of all odontogenic tumors, [2][3][4][5] most commonly arising in mandible (66.4%) followed by maxilla (33.6%). [2,3] According to World Health Organization (WHO), OM is classified as a benign tumor of ectomesenchymal origin with or without odontogenic epithelium. ...
... Rudolf Virchow coined the term myxofibroma in 1863, [2][3][4][5] for a group of tumors that had histologic resemblance to the mucinous substance of the umbilical cord. [2,3,5] OM was first mentioned in the literature by Thoma and Goldman in 1947. ...
... [14,15] Posterior Mandible is more frequently affected than the maxilla. [3][4][5][6] According to Reichart and Philipsen, mandibular myxomas accounted for 66.4%, with 33.6% in the maxilla. Whereas 65.1% of mandibular cases located in molar-premolar region, 73.8% were located in same areas of the maxilla. ...
Odontogenic myxoma (OM) is a rare entity of slowly growing benign neoplasm of ectomesenchymal origin, comprising of 3-6% of all odontogenic tumors that histologically presenting spindle-shaped, stellate and round cells within loosely arranged myxomatous tissue stroma. OM originates from the dental papilla, follicle or periodontal ligament with an exclusive location in the tooth-bearing areas of the jaws, association with missing or unerupted teeth. Clinically and radiographically the reported incidence and demographic information of this tumor has wide variability. Most common clinical variant is associated with the impacted tooth and shows local invasion with destruction of adjacent structures and displacement of teeth. Radiographically, common manifestations are multilocular radiolucent areas with well-defined borders and typical soap bubble or tennis racket appearances. This paper presents two rare case reports of OM of maxilla along with review discussion.
... The treatment of choice for odontogenic myxoma is Surgical excision with clear margins or curettage followed by cryotherapy to devitalize infiltrating tumor cells. [4,5,6] CASE REPORT A 35 year old patient reported to the Department of Oral and Maxillofacial Surgery Career Post Graduate Institute of Dental Sciences & Hospital, Lucknow (U.P) having a history of swelling and pain in right maxillary posterior tooth bearing area since 1 month. Swelling appeared first followed by pain since 3 week. ...
... It was probably first described by Rudolf Virchow as myxofibroma in 1863. [1] [2] In 1992, WHO defined OM as a locally invasive neoplasm consisting of rounded and angular cells lying in an abundant mucoid stroma. These tumors are rare, benign does not show metastasis but they are locally aggressive involving the maxilla and mandible. ...
... [24] OMs are treated surgically as they are radio-resistant tumors. [25] The lack of capsule and its infiltrative growth pattern are responsible for high rate of recurrence when conservative enucleation and curettage are performed. [12] OMs show a locally aggressive behavior and high recurrence and, hence, call for radical resection. ...
Odontogenic myxoma comprises 3-6% of all odontogenic tumors. Odontogenic myxomas are relatively rare benign mesenchymal tumors found exclusively in the tooth-bearing areas of the jaw and are usually located centrally in the mandible. Soft-tissue localization is rarely seen and is classified as peripheral myxoma. Peripheral myxoma is slow growing and less aggressive, as compared to the central myxoma. It has a low recurrence rate. Till date, only few cases of maxillary gingival myxomas are reported in the literature. Here, we present an unusual case of primary peripheral odontogenic myxoma occurring in the gingiva of anterior maxilla in a 41-year-old female patient.
... Odontogenic Myxoma constitutes about 3-6% of total odontogenic tumors. Odontogenic Myxoma occurs commonly in the mandible and their presen-tation in the maxilla is rare [12]. Radiographically, the tumor presents as a unilocular or multilocular radiolucent lesion with well-defined borders and fine, bony trabeculae within its interior structure, expressing as "honeycombed", "soap bubble", or "tennis racket" appearance. ...
Odontogenic myxoma is a rare and locally invasive benign neoplasm found exclusively in jaws. It presents local invasiveness and tendency to recurrence. According to the World Health Organization (WHO), the odontogenic myxoma is classified as an odontogenic tumor of ectomesenchymal origin. The odontogenic myxoma is a rare entity found in both jaws while the mandible is involved more commonly than the maxilla. We present a kind of odontogenic myxoma in a 24-year old male that was found in an unusual location.
... When located in the maxilla, the tumor frequently involves the maxillary sinus. [15][16][17][18] Though the literature refers to the mandible as the most common location of the tumor, the present case has a maxillary involvement. ...
Odontogenic myxoma is an uncommon benign but locally aggressive tumor which exclusively arises from tooth bearing areas. We are reporting a case of a giant slow growing odontogenic myxoma of mandible in a 16-year-old girl causing significant functional and cosmetic problem. Giant size of the tumor has caused facial disfigurement, mental agony and foul smell, because of which the patient confined herself in the house and lived the reclusive social life. Tumor was widely excised and reconstruction done with titanium plate.
