Primary non-neoplastic polyps originating from the nasopharynx have not been reported in the English language literature. We present the clinical and histopathological features of three primary nasopharyngeal polyps. Clinical data of three patients with primary nasopharyngeal polyps treated at the Department of Otolaryngology, The First Affiliated Hospital of Sun Yat-sen University between 2005 and 2015 were analyzed and presented. Three male patients from 45 to 63 years presented with nasopharyngeal masses. CT or MRI examination showed nasopharyngeal space-occupying lesions. Two patients were initially diagnosed with nasopharyngeal angiofibroma and one patient with nasopharyngeal carcinoma. After surgical excision, based on the histological examination, the tissue masses were all diagnosed as inflammatory polyps. Histologically, the polyps demonstrated significant oedema, collagen deposition, leukocytic infiltration, and epithelial remodelling. Primary nasopharyngeal polyps represent a distinct clinical entity and should be considered in the differential diagnosis of nasopharyngeal masses.
