A rare case of a facial-nerve neurofibroma in the parotid gland.
The incidence of solitary neurofibroma of the facial nerve originating in the parotid region is extremely low. We report a case of a solitary neurofibroma in a 30-year-old male, who initially presented with a parotid mass without facial paresis or paralysis. A chain of small nodules had been palpable in the right parotid region for the previous 2-3 years. MRI and CT scans revealed several small ovoid lesions extending from the frontal margin of the parotid gland to the retromandibular region. The lesions were surgically removed. The main trunk of the facial nerve was adherent to the dorsal side of the largest nodule; however, this mass was resected atraumatically. Histopathological examination indicated neurofibroma. The incidence, presentation, diagnosis and surgical treatment of intraparotid neurofibroma are discussed and compared with those of Schwannoma.
