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. Granular cell ameloblastoma is a rare condition, accounting for 3.5% of all ameloblastoma cases that shows marked transformation in the cytoplasm of tumor cells, which are usually stellate reticulum like cells. It is also con...

Peripheral ameloblastoma (PA) is a relatively uncommon odontogenic tumor that is histologically identical to the classic inttaosseous ameloblastoma but it occurs primarily in the soft tissues overlying the toothbearing regions of the jaws and does not exhibit the invasive and aggressive behavior of its intraosseous counterpart.l The origin of PA is thought to be from 1 of 2 sources: extraosseou...

Ameloblastoma is an epithelial odontogenic tumour of the jaw and exhibits diverse microscopic patterns which occurs either singly or in combination with other patterns. Granular cells can occur in various odontogenic and non-odontogenic tumours. Granular cell ameloblastoma is a rare variant of ameloblastoma as making up 1 to 5% of all ameloblastomas that histopathologically has numerous large g...

Ameloblastoma of the mandible is a common benign and locally invasive tumor odontogenic epithelial origin. characterized by its aggressive lytic nature expansion. It mostly involves posterior in elderly patients. The treatment always surgical based on histopathological extent lesion. conservative approach associated with high recurrence rate. have been reported ten years after management about ...

adenoid ameloblastoma with dentinoid is a rare odontogenic tumor. granular cell ameloblastoma also is a less common histological subtype of ameloblastoma. in this report, the patient was a 31‑year‑old male. the lesion was located in the right mandible and was unicystic with well‑defined borders. the tumor tissue was showing a combination of follicular, plexiform, and desmoplastic patterns of am...

BACKGROUND Malignant ameloblastoma, comprising metastasizing ameloblastoma and ameloblastic carcinoma, represents 1.6-2.2% of all odontogenic tumors. Due to its rare nature, malignant ameloblastoma has only been reported in the literature in small case series or case reports. Using the Surveillance, Epidemiology and End-Results (SEER) database, we have performed a population-based study to dete...

AIM Though odontogenic lesions have in common origin from the primitive odontogenic epithelium , there is a diversity in their initiation behavior and growth. The aggressive nature of odontogenic keratocyst similar to ameloblastoma in comparision with the other common odontogenic (dentigerous and radicular) cyst could be due to possible differences in their epithelial linings. PCNA (Proliferati...

OBJECTIVES Some ameloblastomas presumably originate from odontogenic epithelium within the connective tissue of dental follicles and dentigerous cysts. Therefore, it would seem reasonable to discuss as whether odontogenic epithelium proliferations, frankly displaying ameloblastomatous features ("focal ameloblastoma"), should be considered as an "early" ameloblastoma. STUDY DESIGN Histopatholo...

OBJECTIVE The aim of the study was to review all the cases of ameloblastoma seen at the Oral and Maxillofacial Surgery Clinic of the Lagos University Teaching Hospital, Nigeria, between 1980 and 2003. METHODS AND MATERIALS In this retrospective study, case files and biopsy reports of new cases of ameloblastoma covering a 24-year period were retrieved and analyzed for sex, age on presentation,...
