Lesions occurring in the nasal cavity usually present as polypoid masses. Majority of these lesions are non-neoplastic and tumors occurring in the nasal cavity often masquerade as a chronic inflammatory condition. Even though the malignant lesions have a low incidence, they have a relatively greater amount of morbidity. Aim of this study is to 1. Analyse the histopathological spectrum of polypoid lesions of nasal cavity, 2. Frequency of neoplastic and non-neoplastic lesions, 3. to find the age and sex predilection in these lesions. The study comprises of 230 non-neoplastic and neoplastic cases of nasal cavity, over a period of four and a half years in Mahatma Gandhi Medical College and Research Institute, Pondicherry. Because of their nonspecific clinical features, histopathological examination remains as the mainstay for a definitive diagnosis.
