NCI: A carcinoma usually arising from the maxilla and less often the mandible. Symptoms include swelling and paresthesia. It is characterized by the presence of rounded islands of malignant epithelial cells in a fibrous stroma and the benign features of calcifying cystic odontogenic tumor. The clinical course varies from slow growing and locally invasive to rapidly growing and highly aggressive with metastases.
