Desmoplastic ameloblastoma featuring basal cell ameloblastoma: a case report.
The desmoplastic ameloblastoma is a histological variant of ameloblastoma. The neoplastic epithelial islands seen in desmoplastic ameloblastoma are small and ameloblastic cells are rare. Basal cell ameloblastoma is also a rare variant of ameloblastoma, in which the tumor is composed of more primitive cells and has even fewer features of peripheral palisading. This report describes the case of a 17-year-old female with an ameloblastoma in the right anterior maxilla. Orthopantomography and computed tomography showed a well-defined lesion in the right maxilla. A partial maxillectomy for tumor resection was performed under general anesthesia. Histologically, ameloblastic tumor cells were seen with dense collagenous stroma and the tumor cells showed primarily basal cell variants of ameloblastoma. After 7 years of follow-up, clinical and radiographic examinations have revealed no evidences of recurrence.
