We report a case of desmoplastic ameloblastoma in a year-old female with a painless swelling in the left anterior maxillary region.

Abstract Desmoplastic ameloblastoma DA is a relatively rare histological variant of ameloblastoma with specific clinical, radiological, and histological features. This tumor is more commonly seen in the anterior region of jaws as a mixed radiopaque-radiolucent lesion resembling benign fibro-osseous lesions.
Metaplastic bone formation has been reported in few cases. This report describes a lesion in the left anterior maxilla of a young female patient. It arises from odontogenic epithelium and is known for its distinct aggressive clinical behavior and characteristic histologic picture. A characteristic feature is an almost equal distribution in location between the maxilla and mandible. Radiologically, the desmoplastic variant exhibits atypical and varied radiographic features such as: Localized irregular multilocular radiolucency with indistinct borders, or a mixed radiopaque-radiolucent appearance with ill-defined margins similar to fibro-osseous lesion, or a massive expansile osteolytic lesion with honeycomb, mottled or multilocular appearance.
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. Formation of metaplastic bone trabeculae osteoplasia rimmed by active osteoblasts has been described in a few cases. The swelling was slow in growth and present since 4 months.
She had also noticed a slight downward movement of the affected teeth and had mild pain. On examination, a bony hard swelling was seen in relation to 21, 22 and 23 on the buccal aspect measuring about 2.
It was non-tender. Grade I mobility of 21 and 22 was also noticed. Radiographs revealed the presence of irregular radiolucencies with faint radio-opacities in the periapical region of 22 and Lamina dura of the teeth was hazy and teeth were seen to be displaced [ Figure 1 ].
A provisional diagnosis of benign fibro-osseous lesion was made and an incisional biopsy was done.

Treatment[ edit ] Tracheal intubation is difficult in this child with a large ameloblastoma. While chemotherapy , radiation therapy , curettage and liquid nitrogen have been effective in some cases of ameloblastoma, surgical resection or enucleation remains the most definitive treatment for this condition. However, in a detailed study of patients, chemotherapy and radiation therapy was contraindicated for the treatment of ameloblastomas. Conservative treatment requires very careful case selection.
