It is well known that neurofibrom and neurilemmoma are neurogenic tumors. So these tumors occur everywhere neural tissue exists. But they are rarely observed in the oral region, especially the lip. We treated five cases of neurogenic tumors of the lip. Four cases were diagnosed as neurofibrom and one was neurilemmoma. Case 1: A 15-year-old boy had a pigeon egg size tumor at the middle lower lip, and suffered from the lesion for ten years. He had been treated 7 and 8 years before visiting our clinic. The tumor excision was performed in 1966 and 1968 by us. The lesion was diagnosed as neurofibrom by the specimen. Case 2: A 17-year-old boy complained of swelling of the right upper lip. The tumor was excised under local anesthesia and diagnosed as neurofibrom. Case 3: A 23-year-old female's upper lip lesion was excised and diagnosed as neurofibrom histopathologically. Case 4: A 22-year-old female had elastic-hard and well-scribed swelling at the middle of the lower lip. The lesion was diagnosed as plexiform neurofibrom. Case 5: A 24-year-old man had noticed the swelling of the right angle of his mouth 4 years before. Tumor was excised completely and diagnosed as neurilemmoma. No reccurence was observed in these 5 cases till now.
