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

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 histopathology of the lesion was characterized by a stroma containing abundant collagen fibers and scattered desmoplastjc nests or strands composed of spindle-shaped odontogenic epithelial cells. Discussion Clinically, DA may develop in all ages, however, people of the 4th and 5th decade are more prone to be affected.


The lamina dura also was involved.

Osteoplasia may also be present. We are presenting a rare case of desmoplastic ameloblastoma in the ramus region of mandible with regards to its clinical and radiographical viewpoints. Histologically, it is characterized with extensive stromal collagenisation or desmoplasia with small nests and strands of odontogenic epithelium Fig. This case report focuses on a DA which occurred in the mandible of a 26 year-old female.

Ameloblastomas smeloblastoma pronounced desmoplasia. The publisher’s final edited version of this article is available at Oral Oncol. Various immunohistochemical studies have reported DA tumor cells as showing variable expression of S protein and desmin, high expression of caspase-3 and Fas, decreased expression of cytokeratin 19 and high expression of p Desmoplastic ameloblastoma featuring basal cell ameloblastoma: Desmoplastic Ameloblastoma, fibro-osseous lesion.

Histological specimen of a desmoplastic ameloblastoma presenting with irregularly shaped epithelial island, surrounded by narrow zones of loose-structured connective tissue embedded in desmoplastic stroma.


Desmoplastic ameloblastoma – A review

This makes ddsmoplastic radiological differentiation of these two lesions challenging in many cases. A provisional diagnosis of benign fibro-osseous lesion was made and an incisional biopsy was done.

In the focal area, the islands have a swirled hypercellular appearance. However, there is no statistically significant gender distribution as in other types of ameloblastomas.

The surgical specimen had a gourd-like shape, and its cross section contained a solid portion and a cystic lesion arrow. We therefore chose enucleation and curettage and opted for preservation of the inferior alveolar nerve despite understanding the increased risk of tumor recurrence.

J Oral Maxillofac Pathol. Indexed in Web of Science. Radiologically, there is not any agreement among DA reviews as to whether it deals with a radiolucent or mixed radiolucent— radiopaque lesion. The incidence of DA among ameloblastomas ranges from 0.

Among ameloblastoms DA patients, there were 59 Data from different geographical regions seem to suggest a biogeographical pattern in that the relative frequency of DA is slightly higher in Asian ameloblastoms. The surrounding stroma accompanied the cells islands are characterized for significant collagen proliferation.
