Histomorphological Spectrum of Masses of Nasal Cavity in a Tertiary Care Hospital

Introduction: Polypoidal lesions are most common in the nasal cavity. These masses may be congenital, traumatic, inflammatory and neoplastic( benign and malignant) in origin. These nasal masses have a broad histopathological spectrum. Histopathological examination is the only means of determining the nature and patterns of these masses, so that timely intervention can be done. Aims and objectives: To study the histomorphological patterns of polypoidal lesions in a nasal cavity. To categorize the benign and malignant lesions and study the prevalence in relation to age and gender of the patients. Materials and Methods: 100 specimens of polypoidal lesions of sinonasal cavity received over a period of two years in the department of pathology were included in the study. The tissues were subjected to paraffin processing and stained with hematoxylin and eosin. Results: This study included 100 cases, out of which 68 cases were non-neoplastic lesions and 32 cases were neoplastic lesions. Among the 32 neoplastic lesions, 17were benign and 15were malignant in nature. Conclusion: A complete clinical, radiological and histopathological correlation helps to categorize the sinonasal lesions into various non-neoplastic and neoplastic types
