Ameloblastoma is a benign locally invasive epithelial odontogenic tumour comprising 1% of all tumours and cysts arising in the jaws. It is commonly found in the third and fourth decade in the molar ramus region of the mandible. The commonest histopathological variant of this disease process is follicular type having the highest recurrence rate. Ameloblastomas frequently occur in relatively young people, but are rarely seen in people aged 70 years or older.A case of follicular ameloblastoma of mandible in a 72 years old male is discussed here with detail clinical, radiological, and histopathological features.
