Hybrid ameloblastoma – An unusual combination of desmoplastic and conventional ameloblastoma. Table of Contents Alerts. According to locularity, 36 Based on the histological diagnosis, extraction of the lateral incisor, canine, and first premolar was performed under general anesthesia, followed by the enucleation and curettage of the lesion without cutting the inferior alveolar nerve.

The surgical specimen had a gourd-like shape, and its cross section contained a solid portion and a cystic lesion arrow.

Case Report and review Dr. This tumor is more commonly seen in the anterior region of jaws as a mixed radiopaque-radiolucent lesion resembling benign fibro-osseous lesions.

Columnar cells demonstrating reversed nuclear polarity are rarely conspicuous although some islands may show ameloblast-like cells peripherally.

This case report focuses on a DA which occurred in the mandible of a 26 year-old female. Desmoplastic variant of ameloblastoma: Infrequent clinicopathological findings in ameloblastomas, J Oral Pathol Med, A histopathological examination showed a hybrid ameloblastoma with a pronounced desmoplastic pattern and follicular changes.

Radiographic characteristics of cystogenic ameloblastoma.

Ameloblastomas with pronounced desmoplasia. She had also noticed a slight downward movement of the affected teeth and had mild pain.

Hence it can be suggested that if the desmoplasia is caused by tumor cell stimulation of ameloblasyoma fibroblasts, then that stimuli could also affect another cell type, i.


Desmoplastic ameloblastoma with osteoplasia: Review of literature with a case report

Anatomical localization was described in cases. A case of peripheral DA has also been reported recently. First, radiographically, DAs are apt to be mismatched with fibro-osseous lesions. This makes the radiological differentiation of reivew two lesions challenging in many cases. Extensive desmoplasia was seen throughout the stroma compressing the epithelial islands [ Figure 3 ]. It has been reported that DA exhibits more ameloblatsoma behavior than other types of ameloblastoma.

This indicates the greater aggressive potential of conventional follicular ameloblastoma as compared to DA as tenascin has been observed in unstable environments like neoplasia. The most striking feature which separates DA from conventional ameloblastoma is the presence of extensive stromal desmoplasia with an abundance of thick collagen fibers which compress the odontogenic epithelial islands.

The radiographic revieww of DA also differ from the conventional ameloblastoma. The lamina dura also was involved. DA may be defined as a benign but locally invasive variant consisting of proliferating, irregular, often bizarrely shaped islands and cords of odontogenic epithelium of varying sizes embedded in a desmoplastic connective tissue stroma. In the present study, we describe a novel case of hybrid ameloblastoma and present a concise review in the scientific literature to summarize the clinicopathologic characteristics of hybrid ameloblastoma.

The present case had an admixture of DA component with conventional ameloblastoma tissue, which ameloblastomx why we consider that it was a modulated tumor rather than a collision tumor. Among these 11 patients, two suffered from recurrence after resection and four after enucleation, the treatment methods of other five cases were not mentioned.

Prospective studies with regular and long term follow-up are needed to provide the necessary information before any conclusions reviww this aspect can be drawn.

Apart from 1 case without mentioned of age, the age and gender distributions of cases DAs were listed in Fig. A panoramic radiograph revealed a radiolucent lesion with a well-defined border and root displacement of the canine and first premolar without root resorption Desmoplasfic 2.

Involved teeth may be displaced with cortical plate ameloblaastoma. Clinical features Age and gender distribution Apart from 1 case without mentioned of age, the age and gender distributions of cases DAs were listed in Fig. There were no post-operative complications. Desmoplastic Ameloblastoma a Hybrid Variant: These expressions might contribute to amelobladtoma distinct characteristics of DA. The lesion was treated via enucleation and curettage of the marginal bone and fenestration.

DA displays a significantly higher recurrence rate after enucleation than after resection [ 3 ]. A painless swelling or bony expansion are the most conspicuous clinical manifestation in most cases [ 2 — 5 ].
