Clinicopathological study of non-neoplastic and neoplastic sinonasal lesions

In this retrospective study, comprising of 88 cases, various sinonasal lesion both common and rare are studied. All lesions were described, diagnosed histopathologically and classified as per WHO classification. The sample consist of patient in the age group 10 years to 70 years. The study also compares sex differences, symptomatology and the relative incidence of various lesions. The commonest site was nasal cavity, followed by paranasal sinuses. They occur commonly in second and third decade with predominance in males. Out of 88 sinonasal lesion, 73 were non-neoplastic, 10 were benign and 5 were malignant. Amongst non-neoplastic lesion Inflammatory polyp was most common and Inverted papilloma was most common amongst benign lesion. Amongst the malignant lesion commonest lesion was sqaumous cell carcinoma. Sinonasal lesion have wide range of possibilities, so high degree of suspicion with early histopathological examination to exclude or confirm malignancy is essential.
