Histopathological study of polypoidal lesions of the nasal cavity - A cross sectional study

Background & Objectives: Lesions of nasal cavity present difficulty in their diagnosis, prognosis and management because of unusual clinicopathological features. This study was done to evaluate the nasal polyps with regard to age, sex distribution and histologic types. Methods: The present study included 70 polypoidal lesions of the nasal cavity. The study period constituted from January 2003 to December 2006. All the tissues were fixed in 10% formalin, processed stained with H & E and studied for various histopathological features. Results: Simple polyps accounted for 88.57% of total cases and neoplastic polyps accounted for 11.42%. Of the simple polyps non allergic polyps accounted for 58.06% and allergic polyps for 41.93%.Seventy five percent of neoplastic polyps were benign and 25% were malignant. All the malignant polyps in the study were squamous cell carcinomas. Interpretation & Conclusion: The majority of the nasal polyps sent for histology are simple polyps. A variety of benign and malignant lesions of the nasal cavity may present as polyps, hence all polyps need histological examination.
