Introduction Ameloblastoma is the most common borderline odontogenic tumor of epithelial tissue origin. The present case exhibited abundant collagen fibers in the connective tissue stroma. Indexed in Web of Science. Histopathology showing odontogenic epithelium like areas in between dense collagen tissue fibers. A year-old female reported with a swelling in relation to the upper front teeth. Ameloblastoma clinical, radiographic and pathologic study of desmoplastic ameloblastoma, J Oral Maxillofac Surg, The following features are usually observed during microscopic examination: College of Dental Sciences and Research, Mullana, Haryana, India with an asymptomatic swelling of spontaneous origin in her left maxilla that had started one year previously.

Desmoplastic Ameloblastoma: A Case Report

Columnar cells demonstrating reversed nuclear polarity are rarely conspicuous although some islands may show ameloblast-like cells peripherally. Pathology of the desmoplastic ameloblastoma. Ameloblastoma, anterior, desmoplastic, mandible.


Pathology and Genetics of Head and Neck tumorsL. Br J Oral Maxillofac Surg. Histologically, the features were consistent with those of desmoplastic ameloblastoma Figure 5. Immunoexpression of transforming growth factor beta in desmoplastic ameloblastoma.

Desmoplastic ameloblastoma in the mandible. Desmoplastic ameloblastoma a hybrid variant: A year-old male was referred to our hospital complaining of a swelling in the right premolar amelob,astoma of the mandible. Gender, age, tumor site, radiographic imaging findings, and pathological type were retrieved, collated, and analyzed. This makes the radiological differentiation of these two lesions challenging in many cases. The present case, too, lacked typical akeloblastoma of ameloblastoma and was difficult to diagnose correctly.

The panoramic radiograph, conventional computed tomography and magnetic resonance images of desmoplastic ameloblastoma are not specific; they are compatible with those of fibro-osseous lesions and can mimic the radiographic appearance of fibrous dysplasia, chronic sclerosing osteomyelitis, and if well-circumscribed, an ossifying fibroma.

Intra-oral periapical radiograph showing irregular radiolucencies with faint radio-opacities. Clinically, this tumor has a predilection for occurrence in the anterior or premolar region of the maxilla or the mandible. Report of a case and brief review of the English language literature.

The radiological and histological findings of poor encapsulation and ill-defined borders warrants a long-term follow-up. Immunohistochemical profiling of ameloblastomas using cytokeratin, vimentin, smooth muscle actin, CD34 and S J Oral Maxillofac Pathol.

Table of Contents Alerts. Up until now, less than patients have been reported in the literature. Points in favor of myxoma included its female preponderance, potential to attain considerable size without noticeable signs and symptoms, association with missing tooth canine in this caseits predilection for premolar—first molar region in the maxilla and diffuse ill -defined borders on radiographs.


Peripheral palisading columnar cells at basal layer, hyperchromatic Cells show reverse polarization away from basement membrane Vickers-Gorlin change Stellate reticulum-like cells, suprabasal cells composed of loosely arranged angular cells No dentin or enamel formation Many subtypes known and are most commonly described in the context of conventional ameloblastoma likely have no prognostic significance Follicular: None, Conflict of Interest: Infrequent clinicopathological findings in ameloblastomas, J Oral Pathol Med, Desmoplastic ameloblastoma in Indians: Lamina dura of the teeth was hazy and teeth were seen to be displaced [ Figure 1 ].

The relative frequency of hybrid lesions was reported to be 4. How to cite this URL: Desmoplastic variant of ameloblastoma in Chinese patients. A histopathological examination showed a hybrid ameloblastoma with a pronounced desmoplastic pattern and follicular changes.
