Clinicopathological analysis of sinonasal lesions

Abstract

The sinonasal tract is exposed to a variety of infections, chemical irritants, antigens and trauma giving rise to diverse inflammatory as well as neoplastic lesions. The aim was to study the clinicopathological profile of lesions of nose and paranasal sinuses in this area of western Maharashtra. The study included 59 biopsies/resection specimens received in the department during Jan 2015 to June 2019. Clinical and pathological details were analysed. There were 33 females and 26 males. Out of 59 cases, 46 were nonneoplastic and 13 neoplastic, with 10 benign and three malignant. The most common nonneoplastic lesion was sinonasal polyp (42 cases). Other nonneoplastic lesions included three cases of mucormycosis and one case of rhinosporidiosis. In the benign neoplasms, there were three cases of hemangiomas, two hamartomas, two inverted papillomas with one case each of hidradenoma, angiofibroma and schwannoma. We had three malignant tumors, one case each of, melanoma, poorly differentiated carcinoma and squammous cell carcinoma. Nonneoplastic lesions were much more common than neoplastic ones in the sinonasal tract. Histopathological examination plays an important role in correct diagnosis and management.
