Peripheral ameloblastoma of the pterygomandibular space: A case report

Peripheral ameloblastoma is a rare benign tumor of the oral and maxillofacial region with similar histologic features to central ameloblastoma. It arises from rests of odontogenic cells and epitheliums and usually found in the tooth-bearing gingival area of the jaw. We report a case of peripheral ameloblastoma in the pterygomandibular space of a 60-year-old male patient. It is important to note that the lesion occurred in the extragingival area is rarely reported. We suggest that the peripheral ameloblastoma might occur outside of the jaw and report its unique clinical features.
