The development of a neurofibroma in the temporal and parotid regions of the facial nerve is rare. We report a case occurring in a 32-year-old male, where the initial presentation was a parotid mass. Cytologically this was initially thought to be a pleomorphic adenoma. However, the diagnosis was then changed to a schwannoma and finally a neurofibroma after complete excision of the lesion. The case illustrates how fine needle aspiration cytology under ultrasound guidance, and even histological examination of an incision biopsy can sometimes fail to give the correct diagnosis. In this case magnetic resonance imaging was used to help plan definitive surgery.
