However there are a few studies on these lesions especially giant cell lesions reported from India. Hence this study was designed to provide a demographic data on the odontogenic tumors and giant cell lesions reported from our institute located in the city of Hyderabad. Hyderabad is the capital city of the southern state of Andhra Pradesh in India. A retrospective analysis of odontogenic tumors and giant cell lesions of jaws reported in our institute between the years 2000 and 2009 was done and this data was compared with previous reports from different parts of the world and India. Methods Biopsies of the lesions received between the years 2000 and 2009 were reviewed and patient s history clinical radiological and histopathological characteristics were analyzed. Results A total of 77 biopsies were received during the nine year study period. These lesions were more frequently seen in the males in a younger age group and showed a predilection for the mandible. Most of them presented as radiolucent slow growing and painless lesions. Ameloblastomas constituted the majority of odontogenic tumors while central giant cell granulomas constituted the majority of giant cell lesions. Conclusion These lesions showed a definite geographic variation with ameloblastomas being the most common odontogenic tumors and odontomas being relatively rarer lesions in our region. Introduction The oro-facial region including the jaw bones maxilla and mandible is a site for a multitude of neoplastic conditions 1 . .
