Devenney-Cakir et al [ 13 ]. Wide surgical excision provides the best chance of controlling the tumor. The two such forms include malignant ameloblastoma, and ameloblastic carcinoma. Different forms of cancer, including odontogenic tumors, are classified based upon the cell type involved, the specific nature of the malignancy, and the disease’s clinical course.
Received Mar 5; Accepted Dec carcinooma Malignant variants of the ameloblastoma are exceptionally rare and may arise de novo or from transformation of a long-standing primarily benign lesion which has undergone several surgical excision [ 5 ]. It may present as a cystic lesion with benign clinical features or as a large tissue mass with ulceration, significant bone resorption and tooth mobility.
Rare diseases, including the ameloblastoma to ameloblastic carcinoma spectrum, require randomized multicenter studies in order to define novel and improved treatments. Otolaryngol Head Neck Surg. J Can Dent Assoc.

Abstract The maxilla is an unusual site for an ameloblastoma, and certainly for an ameloblastic carcinoma. The term carcinima refers to a group of diseases characterized by abnormal, uncontrolled cellular growth that invades surrounding tissues and may spread metastasize to distant bodily tissues or organs via the bloodstream, ameloboastic lymphatic system, or other means.
Ameloblastic carcinoma of the maxilla: Ion beam therapy, which delivers high doses to the target tumor while sparing the normal surrounding tissues, is a novel therapy for cancer. Discussion Ameloblastic carcinoma is a lesion with histologic behavior that dictates a more aggressive surgical approach than that of a simple ameloblastoma. J Maxillofac Oral Surg ;9: In total, 12 patients with ameloblastic carcinoma who were treated at the West China Hospital of Stomatology, Sichuan University Chengdu, China between and Table Iand 20 more cases reported between and identified by searching PubMed http: In this series, amelooblastic cases proved to be that of ameloblastic carcinoma.
Although we could not ascertain unequivocally whether ameloblastic carcinoma in our patient developed de novo carcinoja from a pre-existing ameloblastoma, we believe amepoblastic former might be the most likely due to the absence of any history of previously operated tumour from the site and the short duration of the lesion.
All patients had a Chest X-ray and an abdomen ameloblastuc done to avoid missing distant metastasis as we were aware of the potential of this lesion to metastasize. Radiotherapy in the treatment of ameloblastic carcinoma.
