Ameloblastoma
A. Definition
Ameloblastoma is a tumor derived from cells - embryonic cells and are formed of cells - the cells berpontesial for the formation of enamel. These tumors are usually slow-growing, histologically benign but clinically malignant neoplasm is, occurs more frequently in the body or ramus of the mandible than the maxilla and can be encapsulated or not encapsulated.

Definition of Ameloblastoma ( amel, meaning enamel and blastos, meaning germ) is a rare, benign tumor of odontogenic epithelium (ameloblasts, or outside portion) much more commonly appearing in the lower jaw than the upper jaw. It was recognized in by Cusack. This type of odontogenic neoplasm was designated as an adamantinoma .
These tumors are rarely malignant or metastatic (that is, they rarely spread to other parts of the body), and progress slowly, the resulting lesions can cause severe abnormalities of the face and jaw. Additionally, because abnormal cell growth easily infiltrates and destroys surrounding bony tissues, wide surgical excision is required to treat this disorder.
