Abstract: This was a retrospective study of 115 cases of space occupying lesions of nasal cavity, Paranasal sinuses and Nasopharynx for a period of 2 years. The aim of this study is to analyse the spectrum of Histopathological diagnosis of mass lesions in these sites. A variety of non-neoplastic and neoplastic lesions are commonly encountered in these sites in clinical practice. Clinically, most of these lesions are polypoidal and resemble each other; diagnostic imaging also could not provide definitive diagnosis in many of these cases. Hence Histopathological examination was mandatory for definitive diagnosis, so that timely intervention could be done. In our study, most of the Sino nasal mass lesions are non-neoplastic (inflammatory polyp being the commonest among them) and the non-neoplastic lesion of adenotonsillar hypertrophy was the most common nasopharyngeal lesion.
