Radiation Oncology/Head & Neck/Ameloblastoma


 * First recognized in 1827 by Cusack JW
 * Designated as adamantinoma in 1885 by the French physician Louis-Charles Malassez
 * Finally renamed to the modern name ameloblastoma in 1930 by Ivey and Churchill
 * Rare, benign or cancerous tumor of odontogenic epithelium (ameloblasts, or outside portion, of the teeth during development)
 * Much more commonly appearing in the lower jaw than the upper jaw
 * Four types of ameloblastoma have been described by the WHO 2017 classification:
 * Conventional (solid/multicystic) type
 * Unicystic
 * Peripheral/extraosseous
 * Metastasising (malignant)
 * Surgical resection or enucleation remains the most definitive treatment for this condition
 * Chemotherapy, radiation therapy, curettage and liquid nitrogen have been effective in some cases of ameloblastoma
