Histopathological Study of Sinonasal and Nasopharyngeal Lesions in a Tertiary Care Hospital Over the Period of 2 Years

Abstract

Introduction: A variety of inflammatory, non-neoplastic and neoplastic masses involving nasal cavity, paranasal sinuses and nasopharynx are commonly encountered in ENT department.[1] This study was undertaken to note the various histopathological patterns of nasal lesions, their classification and relative distribution of various lesions with regard to age and sex in our setting.
Materials and Method: A retrospective study of 127 cases was conducted in the pathology department of B.J Medical college. Demographic detail and detailed clinical and radiological findings were collected. All the biopsies were fixed with 10% buffered formalin. Haematoxylin and eosin staining were done after routine tissue processing.
Results: Out of total 127 cases, 101 cases were non-neoplastic while 26 cases were neoplastic. Among the non-neoplastic lesions, the most common were polyps followed by fungal infection. In neoplastic lesions, 11 were benign lesions while 15 were malignant. Inflammatory polyp was the most common non-neoplastic lesion, Inverted papilloma was the commonest benign lesion while Sino nasal carcinoma was the malignant one.
Conclusion: Histopathological evaluation is always necessary for proper evaluation of Sino-nasal and naso-pharyngeal masses.
