[Co-existence of nasopharyngeal carcinoma and sinonasal paraganglioma: a case report].

Abstract

Paragangliomas are very rarely seen in the nose, paranasal sinuses and nasopharynx. The development of paraganglioma concurrently with nasopharyngeal carcinoma in the same region has not been reported to date. In this study we reported a 59-years-old a female case of nasopharyngeal carcinoma who underwent radiotherapy six years ago and got the diagnosis of sinonasal paraganglioma in the same region during follow-up and underwent nasal endoscopic excision.
