Histopathological study on the spectrum of various sinonasal lesions

Background: A variety of neoplastic and non-neoplastic conditions involve the nasal cavity and paranasal sinuses, amongst which the prevalence of non-neoplastic sinonasal lesions in the general population is 1-4%. It can give rise to a very diverse assay of neoplasms i.e., about 1% of all malignancies. Methods: The study was conducted in the Department of Pathology Mahadevappa Rampure Medical College over a period of two years (2019-2021). A total of 30 cases of sinonasal tract lesions were identified and their histopathological examination was carried out and special staining was done wherever necessary. Results: Out of 30 sinonasal cases, 16 lesions were inflammatory, seven lesions were benign neoplastic lesions and the other seven were malignant. Nasal polyps were the most common inflammatory lesions, mostly in females. Out of seven malignant lesions, squamous cell carcinoma was found in three lesions, and in benign lesions, sinonasal papillomas were found in five lesions. Conclusion: Various lesions of the sinonasal tract including non-neoplastic, benign, and malignant can occur in any age group and both sexes.
