Abstract
A 46-year-old man was referred to our hospital for treatment, complaining of swelling on the right mandibular molar region. Radiographic examination revealed a well defined multilocular radiolucent lesion with root resorption of right lower anteriors and molars. Following biopsy, a diagnosis of unicystic ameloblastoma of mural type was made and hemimandibulectomy was performed under general anesthesia. Histopathological examination of the surgical specimen exhibited a unicystic ameloblastoma of luminal, intraluminal, and mural type. Intraluminal proliferation was of plexiform pattern and mural proliferation showed unusual histopathological findings, which revealed follicular, acanthomatous areas coexisted with desmoplastic areas. This mural picture was similar to the so-called ’hybrid lesion of ameloblastoma’, whose biological profile is not elicited due to the lack of adequate published reports. Two years follow up till date has not revealed any signs of recurrence.
