BACKGROUND Origin of adenomatoid odontogenic tumor (AOT) has long been a controversy, and the issue of it being a neoplasm or hamartoma was a subject of debate for a long time. Earlier it was grouped under a mixed group of odontogenic tumors considering the varying degrees of inductive changes. Recently, the WHO classification states that the presence of hard tissue within AOT was not due to in...

background and aims. odontogenic cysts and tumors have a wide spectrum of clinical characteristics that lead to the different management strategies. since definite diagnosis is difficult in some cases, it has been suggested that cd56 may be a candidate marker for definitive diagnosis of some odontogenic tumors. the present study was designed to examine cd56 expression in lesions with histopatho...

BACKGROUND The purpose of the study was to correlate the provisional diagnosis of pericoronal radiolucencies associated with impacted, embedded, or unerupted teeth with the histopathologic diagnosis, and also to emphasize the importance of early detection for better diagnosis and management. METHODS This is a retrospective study involving 18 cases of pericoronal radiolucencies associated with...

introduction: a keratocystic odontogenic tumor is a benign intra-bone mass originating from dental lamina or its residue. it represents 2–11% of jaw cysts, and has a slow but aggressive growth. the evaluation of molecular characteristics, immunohistochemistry, and genetic expression currently have no established classification regarding the evolution and pathophysiologic pattern of these lesion...

Adenomatoid tumors of Genito-urinary Tract are rare neoplasias, with benign behaviour, and usually are diagnosed incidentally. Adenomatoid tumor of Kidney is even rarer. We report a case of adenomatoid tumor of left kidney in a 53-year old woman who sought evaluation because of vague abdominal pain for one year. During the investigation, aexophytic complex cystic lesion (10x8 cm) in the upper p...
