Abstract
Background: Sinonasal mass is a common finding in the Otorhinolaryngology Department. These can be non-neoplastic or neoplastic. Nasal obstruction is the most common clinical presentation. Imaging studies are not always conclusive in these cases. So, the present study aimed at clinical presentation and histopathological classification of sinonasal masses. Methods: All the specimens received as sinonasal mass were included in the present study. The tissues were routinely processed for histopathological examination and were stained by Hematoxylin and Eosin stain. Special stains were used wherever required. Immunohistochemistry was carried on cases with diagnostic difficulties. Result: Non-neoplastic lesions outnumbered the neoplastic lesions. Among the neoplastic lesions, benign tumours were more common than malignant tumours. Non-neoplastic lesions and benign tumours were commonly seen middle age group while malignant tumours were seen in adult patients. Males were predominantly affected in non-neoplastic lesions and benign tumours. Malignant tumours showed female dominance. Nasal obstruction was the most common complaint. Overall, inflammatory nasal polyps were most common lesions. Inverted papillomas were most common benign tumours. Sinonasal undifferentiated carcinomas accounted for majority of malignant tumours. Conclusion: Sino-nasal masses or polyps can be non-neoplastic or neoplastic lesions and histopathological examination remains the mainstay in differentiating these lesions. DOI: 10.21276/APALM.1207
Highlights
The nasal cavity and paranasal sinuses are collectively referred as sinonasal tract
These deleterious exposures lead to formation of tumour like and neoplastic conditions.[1]Most of these lesions in Otorhinolaryngology Department present as polypoid masses, making it difficult to distinguish non-neoplastic polyps from polypoid neoplasms clinically.[2]
Inflammatory polyps are a common cause of nasal obstruction, with a prevalence of 4% in the general population.[3]Benign tumours are relatively common, but malignant neoplasms are rare
Summary
Sinonasal area is exposed to various infective agents, chemicals, antigens, mechanical and many other influences.
