A Case of a Huge Solitary Neurofibroma Extending from the Tongue to the Floor of the Mouth

We describe a case of huge solitary neurofibroma in the oral cavity. A 59-year-old man with a history of dysphagia presented with swelling of the tongue. Magnetic resonance (MR) images showed a lesion extending from the base of the tongue to the floor of the mouth located above the mylohyoid muscle. The dimensions of the enucleated tumor were 95 mm in length, 65 mm in width, and 15 mm in thickness. Histopathological examination revealed that the lesion was a diffuse neurofibroma.
