A clinicopathological study of masses arising from sinonasal tract and nasopharynx in north Bengal population with special reference to neoplasms

Abstract

Abstract Introduction: Various masses arise from sinonasal tract and nasopharynx, which are embryologically distinct. Aims and objectives: A cross-sectional study for 1 year in a tertiary care hospital was carried out. Materials and methods: Either incisional biopsy or surgical excision sample with proper history and imaging was collaborated. Results: The total percentage of these tumors during the 1-year period was 3.52%. A total of four nonspecific lesions, 49 non-neoplastic masses, 17 benign neoplastic masses, and 24 malignant neoplastic masses were found. Conclusion: Non-neoplastic masses were the majority in number (52.12%). Among the neoplastic masses (43.61%), malignant neoplasms constituted 25.53%, a vast majority being nasopharyngeal carcinomas. Immunohistochemistry further helped to differentiate undifferentiated carcinomas into epithelial and lymphoid malignancies.
