Clinico-pathological study was carried out in these cases. A provisional diagnosis was made after clinical assessment and radiologic investigations, but final diagnosis was made after histopathologic examination.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Observations:<\/jats:title>\n                    <jats:p>The number of non-neoplastic lesions were more than the neoplastic lesion, 60% versus 40% respectively. In the neoplastic group, 19.8% and 23.76% patients presented with benign and malignant lesion, respectively. The incidence was more predominant in the age group of 11-20 years (22.72%) with male to female ratio of 1.08:1. In our study, among non-neoplastic lesions the occurrence of sinonasal polyps was highest seen in 80.30% cases. In neoplastic lesions, angiofibroma was most common benign lesion seen in 35% cases. Carcinoma nasal cavity was the commonest malignant lesion seen in 45.83% cases. In 3.63% patients, clinical and radiologic diagnosis was not correlated with histopathologic diagnosis. Only two cases required immuno-histocytochemistry to confirm the final diagnosis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>We concluded that for proper evaluation of a sinonasal mass, clinical, radiologic, and histopathologic evaluation should be carried out conjointly in all the cases. Histopathology always gives a confirmatory diagnosis but in few cases immuno-histocytochemistry becomes the ultimate diagnostic technique for correct and timely intervention.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/0975-5950.111375","type":"journal-article","created":{"date-parts":[[2013,5,4]],"date-time":"2013-05-04T05:58:36Z","timestamp":1367647116000},"page":"180-186","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":29,"title":["Clinico-pathological profile of sinonasal masses: An experience in tertiary care hospital of Uttarakhand"],"prefix":"10.4103","volume":"3","author":[{"given":"S.
