Abstract

Introduction: Nasal polyps are polypoidal masses arising from mucous membranes of nose and paranasal sinuses. They are overgrowths of the mucosa that frequently accompany allergic rhinitis. They are freely movable and nontender.
Aims and Objectives: The purpose of this study was to study the histopathologic spectrum of polypoidal lesions of the nasal cavity.
Materials and Methods: The study comprised of 100 condivutive cases of polypoidal lesions in the nasal cavity, received in the department of pathology. The age and sex of the patients were recorded. The tissues were routinely processed for histopathologic divtions and stained with haematoxylin and eosin stains. Special stains like Periodic acid Schiff (PAS) was done wherever applicable. The cases were classified into neoplastic and nonneoplastic lesions. The neoplastic lesions were further classified according to WHO classification on histopathologic examination.
Results: Analysis of 100 polypoidal lesions in the nose and paranasal sinuses with clinical diagnosis of nasal polyps, revealed 66 cases were nonneoplastic and 34 were neoplastic;17 (50%)were benign and 17(50%) were malignant. True nasal polyps both inflammatory and allergic together comprised 44 cases of the 100 polypoidal lesions in the nasal cavity. Angiofibroma and inverted papilloma were the most frequent benign tumour accounting for 12/17(0.7%). The most common malignant tumour was anaplastic carcinoma 7/17(0.4%). Nonneoplastic and benign tumours were common in younger age groups whereas malignant tumours were most common in older males.
Conclusion: The majority of polypoidal lesions in the nasal cavity are nonneoplastic.
