INTRODUCTION Ameloblastomas are odontogenic epithelial, locally invasive tumors of slow growth and mostly of benign behavior. Their frequency is low (they account for 1% of all head and neck tumors and about 11% of tumors of dental origin). Malignant variations of ameloblastoma are malignant ameloblastoma and ameloblastic carcinoma. They constitute less than 1% of all ameloblastomas. We present...

The ameloblastoma is a benign neoplasm of epithelial odontogenic origin, slowly growing, locally invasive and it is the most common odontogenic tumor in the jaws. Histologically, various types have been described in literature. The desmoplastic variant is rare and characterized by difference in the typical findings of ameloblastoma, including localization, radiographic and histological features...

Ameloblastoma is a true benign odontogenic neoplasm with many classical histological variants, common being follicular and plexiform types. Hemangiomatous amelobalstoma is a very rare variant that shows unique histopathologic characteristics varying from conventional ameloblastoma. We present a rare variant of ameloblastoma in a 35-year-old female patient with a swelling over left mandibular re...

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 ...

Background. Calretinin is a 29 kDa calcium-binding protein of the EF-hand family which is expressed in a variety of normal and tumorigenic tissues. Its expression in odontogenic epithelium during odontogenesis and in neoplastic odontogenic tissues has been demonstrated. Unicystic ameloblastoma poses a diagnostic challenge, as its histologic presentation can be sometimes mistaken for keratocysti...

BACKGROUND The aim of the study is to detect apoptosis in granular cell ameloblastoma by annexin v affinity assay, a novel technique. MATERIALS & METHODS Excitional biopsy of two patients with granular cell ameloblastoma were fixed in buffered formalin and later embedded in paraffin wax. Blocks were sliced into 3m thick sections for routine histological and subsequent immunohistochemical exam...

Unicystic ameloblastoma, a variant of solid or multicystic ameloblastoma is commonly reported to occur in third decade and encountered in the posterior mandible with a biologically low-grade course and with limited recurrence potential. Clinically, it frequently manifests as a painless swelling, which can be accompanied by facialde formity, malocclusion and paresthesia of the affected area. His...

Ameloblastoma is a benign odontogenic neoplasm which frequently affects the mandible. The term ameloblastoma includes several clinico-radiological and histological types. Apart from the most commonly encountered clinicopathologic models there are few variants, whose biological profile is unknown or not elicited. The reason for lack of understanding is the scarcity of case report published in th...

Ameloblastoma is a benign odontogenic tumor. These are usually asymptomatic until a large size is attained. Ameloblastoma has tendency to spread locally and has a high recurrence rate. Majority of ameloblastomas (80%) arise from the mandible. Ameloblastoma arising from anterior mandibular region (symphysis-menti) is rare. Very few cases of midline anterior ameloblastomas are reported in the lit...
