Maxillary sinus schwannoma [PDF]

BMJ Case Reports, 2018
Schwannoma (neurilemmoma) is a benign tumour that arises from the Schwann cells which cover the nerve sheaths of the peripheral or autonomic nervous system especially the sympathetic system. Reported cases of schwannoma arising from the sinonasal tract are rare. We report a case of a 28-year-old man who presented to otolaryngology—head and neck surgery
