INTRODUCTION: malignant tumors of the nose and paranasal sinuses represent 1% of malignant neoplasms of the body and 3% of those originating in the upper respiratory tract; the most common is epidermoid carcinoma. OBJECTIVE: determine the concordance between results of malignant neoplasms detected by pathology and those detected by computed tomography. MATERIAL AND METHODS: of histopathological results for malignant neoplasms of the nose and paranasal sinuses, obtained from 2012 to 2015, those with interpretation were included. We determined how many neoplasms were diagnosed as such in image studies and calculated the concordance with the Kappa coefficient. RESULTS: of 192 histopathological results of malignant neoplasms of the nose and paranasal sinuses, in the period studied, 42 had tomography and interpretation; the non-concordant proportion was 15 (35.7%) cases, the concordant proportion was 27 (64.3%) cases, and the observed proportion was 0.64; the expected proportion was estimated at 0.26, calculating a Kappa coefficient of 0.51 with "moderate" strength concordance. CONCLUSIONS: we can conclude that, to increase diagnostic concordance, it is essential to have a good clinical history and examination of the patient. In extension studies, it is important to have a suspected site of the primary tumor and conduct acquisition protocols and post-process protocols suitable for the head and neck region.
