A 29-year-old healthy patient was submitted for exploration of intraosseous, unicystic lesions of the mandibular angle distal to the wisdom tooth of both sides. Histological investigation of the enucleated cystic lesions revealed bilaterally developed lymphoepithelial cysts (LEC). Healing was uneventful and re-ossification of the bone complete. LEC are rarely diagnosed in oral tissues and usual...

The term Unicystic Ameloblastoma (UA) refers to those cystic lesions that show clinical and radiological characteristics of an odontogenic cyst but on histological examination show a typical ameloblastomatous epithelium lining part of the cyst cavity, with or without luminal and/or mural tumor growth. Till date, lot of controversies exist among oral surgeons and oral pathologists regarding this...

Maxillofacial images must be examined to find pathologies not identified during clinical examination. Unicystic ameloblastoma (UA) extending to the mandibular body and ramus was neglected on initial panoramic radiographic examination. After orthodontic therapy, a huge lesion was observed clinically and through imaging exams. After the conservative surgery, no recurrence was observed during five...

Ameloblastoma, especially maxillary, is a rare benign neoplasm of odontogenic origin. Diagnosis of significant number of lesions is usually established postoperatively, because ameloblastoma, especially the unicystic form, mimics wide range of more frequent jaw lesions. From January 1993 to December 2005, three cases of the maxillary ameloblastoma were surgically treated at our Department. The ...

Ameloblastoma is the most clinically significant odontogenic tumor. There has been no previous comprehensive report from Saudi Arabia about the presentation and prevalence of the tumor. This study aimed to describe the cases of ameloblastoma seen in a biopsy service of a teaching hospital in Saudi Arabia over a 32 year period. The records and archival material of the patients seen during this p...

AIM To evaluate the use of proliferating cell nuclear antigen index in the different histopathological variants of ameloblastoma, such as the follicular, plexiform, and unicystic types, and in ameloblastic carcinoma by immunohistochemical staining. The proliferating cell nuclear antigen index values of the variants of ameloblastomas and ameloblastic carcinomas are compared in order to determine...

PURPOSE The clinical behavior of unicystic ameloblastoma varies according to its subtype. The assessment of its proliferative capacity, neovascularization, and invasiveness using relevant immunomarkers may aid in appropriate surgical therapeutic protocol. METHODS 18 cases of clinically and histologically confirmed unicystic ameloblastoma, categorized as luminal, intraluminal, or mural subtype...

BACKGROUND Odontogenic ameloblastoma (OA) of the jaws is a rare neoplasia of the oral cavity (0.78%) with a 5:1 mandible/maxilla relation, with the molar region and the ascendant ramus being the most affected areas. Comparing our results with the literature demonstrated to us that this tumor may be considered to be a worldwide problem due to the similarity in clinical findings among different e...
