This study was submitted prospectively on 100 patients diagnosed with nasal polyps (diagnosed either clinically or radiologically) with evidence of nasal obstruction,rhinorrhae and headache. from April 2015 till April 2017. All patients had been selected from the outpatient clinics of Al-Zahraa University Hospital and Kobry El Koppa military hospital.

There were 83 male and 17 female. The main presenting symptoms are nasal obstruction and rhinorrhea. Most of the cases was bilateral nasal polyps,. The commonest clinical diagnoses were non-neoplastic simple nasal polyps 84% and about 13% were benign neoplastic, 3% were malignant. The commonest histological diagnosis among nonneoplastic nasal polyps was simple allergic nasal polyp, among benign neoplastic was inverted papilloma most of neoplastic lesions were presented by unilateral nasal polyps,where epistaxis was noticed mostly with vascular tumour and malignant ones. The results show that most of nasal polyps were simple nonneoplastic lesions especailly bilateral ones,also for proper evaluation of nasal polyps clinical, radiological and histopathological evaluation should be done in all patients.
