Odontogenic Myxoma: a study based on biopsy material over a 40-year period.

Aim: Odontogenic tumors, including odontogenic myxomas (OMs) are regarded as rare neoplasms in the human body. Nevertheless, they may be problematic for diagnosis and treatment planning due to possible variations between different races and countries. The aim of the current study was to present the clinicopathologic features of OM in an Iranian population over a 40-year period and compare them with those reported elsewhere.

A retrospective analysis of peripheral odontogenic fibroma in an Iranian population.

Purpose: The aim of this study was to assess the relative frequency of peripheral odontogenic fibroma (POdF) in an Iranian population and to compare the obtained data with previous reports.

Materials And Methods: Archival material was retrospectively analyzed from 1967 to 2007, and all microscopic slides of lesions considered in the differential diagnosis of POdF were retrieved. A diagnosis of POdF was made according to the criteria described by the World Health Organization in 2005.

Comparative expression of calretinin in selected odontogenic tumours: a possible relationship to histogenesis.

Aims: Calretinin, a calcium-binding protein, is expressed primarily in certain subtypes of neurons. It has also been reported to be present in mesotheliomas and other tumours. The aim was to determine the expression of calretinin in selected odontogenic neoplasms.
