OBJECTIVES Odontogenic tumors (OT) represent a specific pathological category that includes some lesions with unpredictable biological behavior. Although most of these lesions are benign, some, such as the ameloblastoma, exhibit local aggressiveness and high recurrence rates. The most common types of ameloblastoma are the solid/multicystic (SA) and the unicystic ameloblastoma (UA); the latter c...

Ameloblastoma is a benign but locally aggressive odontogenic tumor. Worldwide, maxillary ameloblastoma is rare, but its late detection renders adequate treatment difficult. Majority occur in the mandible with about 5-20% occurring in the maxillary bone. Here we report a case of ameloblastoma of the left maxilla in a 35-year-old man. The tumor was presented as a painless swelling in the left fac...

Typical MR images of ameloblastomas on T2-weighted image (WI) or short inversion time inversion-recovery (STIR) show multiple bright high-signal-intensity loci on a high-signal-intensity background. Unilocular cystic-type ameloblastomas show homogeneously bright high signal intensity on T2WI or STIR as a water-like signal intensity. Therefore, it is difficult to distinguish unilocular cystic-ty...

Ameloblastoma, çene bölgesinde görülen bir benign tümördür. En sık 20-50 yaş aralığında izlenir. Mandibulayı maksilladan daha tutar ve %80 oranında mandibular molar bölge ramus ortaya çıkar. Ameloblastoma yavaş büyür, ayrıca kemikte ekspansiyon destrüksiyon yapma eğilimindedir. Güncel sınıflamada ameloblastoma geleneksel, unikistik, ekstraosseöz/periferal metastaz yapan olmak üzere dört gruba a...

Background: Ameloblastoma is the most common benign epithelial odontogenic tumor with malignant potential and usually located in jaw. It constitutes about 1-3% of all tumors cysts jaws. This entity has a very high recurrence rate over 50% even after wide excision. Preoperative diagnosis ameloblastoma can be made by fine-needle aspiration biopsy (FNAB) which used as guide for surgical planning. ...

Amelo blastoma is a neoplasm that originates from odontogenic epithelium. It the second most common of oral cavity. Uni cystic ameloblastomas refer to those lesions show clinical, radio graphic, or gross features jaw cyst, but on histologic examination typical ameloblastomatous epithelium lining part cyst cavity, with without luminal and/ mural growth. Even though lesion not aggressive as solid...

OBJECTIVE To describe ameloblastoma of the jawbone in young Jamaicans, with special emphasis on radiological findings, and to introduce a radiological classification which could assist in the categorization of these cases according to their biological behaviour and hence their subsequent surgical and medical management. SUBJECTS AND METHODS The series comprised all the 18 cases of ameloblasto...

We report the case of a 59-year-old woman who presented with metastatic ameloblastoma involving the lungs, 20 years after resection of the primary tumor in the mandible. The lesions were debulked on multiple occasions with radiofrequency ablation over an eight-year period with local response. There were no complications related to the procedures. We suggest that radiofrequency ablation is a pos...

This is a review of 20 cases of ameloblastomas diagnosed and treated at the Dental Facu ltv, University of Malaya, Kuala Lumpur. The clinical features, histological features and treatment methods are presented. Two basic clinical types namely the conventional (solid/multicystic) and unicystic ameloblastomas showed different recurrence rates. Discrepancies between the recurrent rates in this stu...

Four camels ( Camelus dromedarius ) presented to the Veterinary Teaching Hospital at King Faisal University with maxillary masses. On radiographs, masses were multicystic and expanded bone. The tumors diagnosed by histopathologic examination as conventional ameloblastoma, two cases intraosseous squamous cell carcinoma, central odontogenic fibroma ossification. To authors’ knowledge, this is fir...
