The oxytalan fibers in the stromal tissue suggest that the tumor derived from the epithelial rest of Malassez desmoplastkc the periodontal membrane of a related tooth. A partial maxillectomy for tumor resection was performed under general anesthesia and a transitional maxillofacial prosthesis was placed. The present case, too, lacked typical findings of ameloblastoma and was difficult to diagnose correctly. Radiographically, the intraosseous ameloblastoma is classically described in dental desmopllastic and panoramic films as a multilocular or ‘soap bubble’ radiolucency.

Based on the clinical and radiographic appearance, a provisional diagnosis of odontogenic myxoma was made. On palpation, the swelling was non-tender and the inspectory findings were confirmed. The enucleated sample was firm and had amelkblastoma irregular shape, and its cut surface was solid, whitish, and partially cystic Figure 4.

A partial maxillectomy for tumor resection was per-formed and the involved teeth were removed.

Desmoplastic ameloblastoma in the mandible. Desmoplastic ameloblastoma in the maxilla: Moreover, some suggest that desmoplastic ameloblastoma might arise from epithelial rests of Malassez in the periodontal membrane.

Regarding its origin, it is suggested that desmoplastic ameloblastoma develops from the periodontal membrane of the related tooth. A panoramic radiograph revealed a radiolucent lesion with a well-defined border and root displacement of the canine and first premolar without root resorption Figure 2.

Yoshimura Y, Saito H. In most of the cases, their radiographic appearances are often more typical of the fibro-osseous lesions with well-defined or poorly defined borders.

Desmoplastic ameloblastoma DA is one of the 6 histopathological subtypes of ameloblastoma.

DA is reported to occur in the anterior or premolar region of either maxilla or ameolblastoma. In this case, disappearance of the lamina dura and the periodontal ligament space of the adjacent lateral incisor root was clearly identified.

They speculated that secondary desmoplastic changes occur in the stroma of conventional ameloblastoma or areas of desmoplastiv DA transform into a conventional ameloblastoma. Histologically, the tumor might be misdiagnosed as another odontogenic tumor, as the characteristic palisading layer of ameloblastoma may not be present in all the epithelial clusters, particularly if the biopsy specimen is small.

The mucosa over the swelling appeared normal. A case report ameloblawtoma desmoplastico della mandibola: This aggressiveness may be due to 1 potential to grow to a large size; 2 the common location in the maxilla leading to an early invasion of adjacent structures; 3 the diffuse radiographic appearance, and 4 histologic ameloblastoa of bone invasion.

Fine needle aspiration yielded no fluid. Int J Oral Maxillofac Surg ; Analysis of 17 Nigerian cases. Desmoplastic ameloblastoma DA is a relatively rare histological variant of ameloblastoma with specific clinical, radiological, and histological features.

Case Reports in Pathology

The radiographic features of DA also differ from the conventional ameloblastoma. We performed a clinicopathological analysis of the approximately 30 cases of hybrid ameloblastoma reviewed by Rai et al.

Again, the borders of DA are usually poorly defined. A histopathologic study of ameloblastomas with special reference to the desmoplastic variant. Radiographic examination revealed a mixed radiolucency interspersed with radiopacities with ill-defined borders. Multilocular, mixed radiolucent-radio-opaque lesion. With limited understanding of its biologic behavior and prognosis, the proper treatment strategies for desmoplastic ameloblastoma are not entirely defined so far.

The physical examination revealed facial asymmetry due to swelling on the left side of face which was oval in shape and had a smooth surface. According to Philipsen et al, 13 radiographically aeloblastoma borders suggest an infiltrative process with propensity to recur.

The mixed radiographic appearance is due to osseous metaplasia within the dense fibrous septa that characterizes the lesion, and it is not because of the production of a mineralized product by the tumor.
