Unicystic Ameloblastoma Mimicking Lateral Periodontal Cyst.

Intraosseous unicystic ameloblastoma (UA) is a rare subtype of a true neoplasm of odontogenic epithelial origin: ameloblastoma. Despite its rareness, dealing with UA is problematic. It is usually mistaken for an odontogenic cyst, and biopsy is rarely relevant because of its multiple growth patterns.
