[Intra-oral Perineurioma, a case report].

A 48 year old woman was referred by her general practitioner to an oral and maxillofacial surgeon because of an asymptomatic, slow growing intra-oral tumor since three years. There were no sensory and motor symptoms. A well-defined tumor of 5 cm in diameter was located in the right cheek between the zygomaticus arch and the labial commissure. The skin and the intra-oral mucosa were intact without any change in colour or texture. The MRI showed a solitary mass with benign characteristics. A transoral radical excisional biopsy was performed under general anesthesia. Histopathological examination revealed a rare soft tissue perineurioma tumor.
