A diverse group of lesions may present themselves as polypoidal masses. They may be simple mucosal polyp or a variety of other pathological entities like infective granulomatous diseases, papillomas, vascular masses or malignant neoplasms. A number of deceptively benign looking polyps often turn out to be malignant lesions or vice versa. The aim of our study was to evaluate the Clinical and histopathological correlation of the excised polypoidal masses. Study group included 100 patients with nasal polypoidal masses, who were treated at E.N.T Department, INSTITUTE OF OTORHINOLARYNGOLOGY & HEAD–NECK SURGERY, IPGME&R, KOLKATA, since NOVEMBER 2018 to OCTOBER 2019. It was showed inverted Papilloma showed single as well as multiple sinus involvement,they are both homogenous and heterogenous in density. Few cases showed bony changes and calcification. all cases were not involving any sinuses and had a homogenous density single case of adenocarcinoma involved multiple sinuses with heterogenous density, bone erosion along with calcification single case of Adenocystic Carcinoma involved multiple sinuses with heterogenous density, bone erosion along with calcification out of six cases of Squamous Cell Carcinoma all of them showed multiple sinus involvement,heterogenous density along with bony erosion. Half of the cases had calcification. Keeping these considerations in the mind, all polypoidal masses in nasal cavity justify histopathological examination
