Neurofibromas are derived from the nerve sheath and are commonly located in the head and neck region. It is often related to neurofibromatosis, especially type I which also known as von Recklinghausen's disease of the skin. Intraoral neurofibroma not related to neurofibromatosis is relatively uncommon. We present a case of solitary neurofibroma in a young female who denied family history of neurofibromatosis and lack of other signs of neurofibromatosis, presented with a painless submucosal mass over the left side of the tongue. She received total excision of the tumor and the pathology proved to be diffuse neurofibroma.
