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...

Ameloblastoma is a true neoplasm of odontogenic epithelial origin. Unicystic ameloblastoma refers to those cystic lesions that show clinical, radiographic or gross features of a mandibular cyst, but on histologic examination show a typical ameloblastomatous epithelium lining part of the cyst cavity with or without luminal and/or mural tumor growth. It accounts for 5 to 15% of all intraosseous a...

Unicystic ameloblastoma is a slow-growing tumor originating from the odontogenic epithelium that can be localized within lining of cyst. It commonly affects younger individuals and frequently found in posterior mandible. The classification this based on histopathological characteristics, distinguishing between luminal, intraluminal, mural proliferation epithelium. Treatment options vary dependi...

UNLABELLED Ameloblastoma behavior is related to the potential of tumor cells to inhibit apoptosis and to initiate a proliferative phase. This study was performed to compare the immunoexpression of Survivin with Bcl-2, Bax, and Ki-67 and to associate them with the histopathological type of each variant of ameloblastoma. MATERIAL AND METHODS Using the World Health Organization (WHO) criteria fo...

ameloblastomas are tumors of odontogenic epithelial origin. the term unicystic ameloblastoma is used to describe cystic lesions with clinico-radiographic features resembling an odontogenic cyst, but histologically showing the presence of ameloblastomatous epithelium lining part of the cyst cavity. a large majority of lesions are found in the mandible, and usually cause a painless swelling of th...

The Unicystic Ameloblastoma (UA), represents an invasive polymorphic lesion whose origin is currently unknown, but it presumed to form from the epithelial remains of Malassez sheath Hertwig. It second most prevalent odontogenic tumor, which characterized by being locally and high recurrence. usually presents a predilection for male sex, affecting during third decade life. Clinically, asymptomat...

Ameloblastomas are benign tumors whose importance lies in its potential to grow into enormous size with resulting bone deformity. Unicystic ameloblastoma (UA) refers to those cystic lesions that show clinical, radiographic, or gross features of a mandibular cyst, but on histological examination show a typical ameloblastomatous epithelium lining part of the cyst cavity, with or without luminal a...
