Neurofibromas are frequently present in the skin, but are uncommon in the oral and maxillofacial region. There are three histological variants of neurofibroma: localized, diffuse, and plexiform. The plexiform histological variant of neurofibroma is the least common and is a rare occurrence in the oral cavity. Furthermore, plexiform neurofibroma is usually pathognomonic of neurofibromatosis type 1. A case of solitary plexiform neurofibroma of the tongue with no evidence of neurofibromatosis in a 50-year-old female Chinese patient is reported here. The lesion presented as a single, large, well-circumscribed rounded mass in the left hemi-tongue. The tumour was completely excised. No recurrence was observed at the 6-month follow-up.
