Nonexpansile Unicystic Ameloblastoma: A Rare Case Report

Ameloblastoma is the most common benign odontogenic tumor that has the potential to grow into a large size. Unicystic ameloblastoma (UA) is a variant of the solid or multicystic ameloblastoma. It is a rare (relative frequency 5–22%) benign, locally invasive odontogenic tumor of young age that mimics clinically and radiographically as an odontogenic cyst. Radiographically it may present as unilocualr or multilocular with cortical plate expansion. Conventional radiograph has less advantage to determine their extension into soft tissue. Hence, conventional tomography, cone-beam computed tomography, and magnetic resonance imaging may be used to determine expansion, root resorption and relation with adjacent structures. It has low recurrence rate after conservative therapy. Here, we present a rare case of nonexpansile UA with an unusual presentation in a young male patient.
