Ameloblastoma is true odontogenic tumor of epithelial origin, which is described as locally aggressive with varying chances of recurrence. It is believed to derive from enamel organ, remnants of dental lamina, lining of odontogenic cysts, or basal cells of oral epithelium. Radiologically, it may present as unilocular or multilocular radiolucency commonly. Although conventional ameloblastoma pre...

Ameloblastoma is a neoplasm of odontogenic epithelium, especially of enamel organ-type tissue that has not undergone differentiation to the point of hard tissue formation. It accounts for approximately 10% of all tumors originating from gnathic bones. It exhibits diverse microscopic patterns which occurs either singly or in combination with other patterns. Granular cell ameloblastoma is a rare ...

A 40-year-old man suffered from a repeatedly recurrent desmoplastic ameloblastoma in the right maxillary anterior and premolar regions. During the first visit, the patient was provisionally histopathologically diagnosed with a developmental cyst, and it was confirmed to be unicystic ameloblastoma and resected. Four years later, the lesion recurred, and was diagnosed as a desmoplastic type of am...

Thank you for your attention to our study and wonderful questions. Our reply is as below. Question) The title of the article states that the case is about a glandular odontogenic cyst (GOC) mimicking am-eloblastoma. The history (slow expansion, no symptoms) and the radiographic appearance of the lesion (lobulated, well-defined margin, erosion and perforation of the lin-gual cortex, root resorpt...

Ameloblastoma is a slow-growing and locally invasive epithelial odontogenic tumor of the jaw that runs benign course in most cases. Granular cell ameloblastoma rare subtype ameloblastoma, showing granular transformation its cytoplasm. It considered as an aggressive variant ameloblastoma. Herein, we report case 34-year-old male patient who presented with swelling left cheek for 1-year duration r...

Ameloblastoma is an infiltrative benign neoplasm in the mandible or maxilla that locally aggressive with rare metastasizing capacity. This lesion most common tumor of odontogenic epithelium. However, its occurrence children low, representing only 10–15% all reported ameloblastoma cases. In treating such neoplasms pediatric patients, preservation vital structures as inferior alveolar nerve (IAN)...

The purposes of this study were to investigate the distribution of cytokeratins in the different tissue types of ameloblastoma and to discuss the histogenesis of this tumor. CK19 and CK8, which are markers for odontogenic epithelium, reacted positively to the constituting cells in all types of ameloblastoma. This suggests that all types of ameloblastoma derive from odontogenic epithelium. Howev...

Ameloblastoma is an odontogenic tumor of high frequency and usually occurs as an intraosseous growth. Ameloblastomas frequently recur, sometimes undergoing malignant transformation. These tumors are usually characterized as being multilocular, of the follicular type histopathologically, and invading strongly at the border region of the tumor. More than 10% p53-positive tumor cells give a progno...

Unicystic ameloblastoma is believed to be less aggressive and responds more favorably to conservative surgery than the solid or multicystic ameloblastomas. This report is a rare case of unicystic ameloblastoma of the maxilla that was treated by enucleation under suspicion of a radicular cyst related to a dens in dente. The neoplastic nature of the lesion became evident only when the enucleated ...

The purpose of this report is to document a case of unsuspected ameloblastoma involving the right man dibular subpontic region in a 38-year-old Cambodian female patient. This lesion was purportedly preceded by multiple radiolucencies which were diagnosed as radicular cysts and treated a few times in the past years by enucleation followed by endodontic therapy of the affected teeth. Bridgework r...
