OBJECTIVES
To study the histopathological patterns of masses in the nasal cavity, paranasal sinuses and nasopharynx in Manipur, India.
SETTINGS AND DESIGN

MATERIAL AND METHODS
All cases of specimens of masses in the nasal cavity, paranasal sinuses and nasopharynx from the period of April 2013 to September 2015 were included in the study.

A total of 102 cases were studied during the study period. Age ranged from 6 years to 80 years with slight male preponderance. Non-neoplastic lesions comprised of 59 cases (57.84%) and neoplastic lesions was 43 cases (42.16%). Inflammatory polyp comprised 46 cases (45%) and was the predominant lesion in the non-neoplastic group. Among the neoplastic lesions, malignant lesions (65.12%) predominated over benign lesions (34.88%). Undifferentiated carcinoma was the commonest malignant tumour and sinonasal papilloma was the commonest benign tumour.
