Abstract

<p>Solitary neurofibroma is relatively rare. We report a case of solitary neurofibroma arising in the mucolabial fold of the maxilla. The patient was a 63-year-old man who had no symptoms, except for a painless swelling in the center of mucolabial fold of the maxilla. Intraoral examination revealed a smooth surface, mobile, well-delimited, and elastic soft mass approximately 10 mm in diameter. The clinical diagnosis was a benign tumor. An excisional biopsy of the tumor was performed with the patient under local anesthesia. The tumor did not adhere to surrounding tissues. Periosteum and a clear continuity with blood vessels and nervelike tissues were not observed. Histologically, the tumor was encapsulated and composed of proliferated spindle cells in a myxomatous stroma. Neither café au lait spots nor similar tumors were observed on systemic examination. The final diagnosis was a solitary neurofibroma. About 1 year and a half after the operation, there is no evidence of recurrence.</p>
