Plexiform neurofibromas (PNFs) are one of the most common and debilitating complications of neurofibromatosis type I (NF-I). They account for substantial morbidity, disfigurement, functional impairment and are life threatening. PNFs can also be subjected to transformation into malignant peripheral nerve sheath tumor (MPNST). This complication is refractory to treat due to paucity of effective therapies for malignant soft tissue sarcomas in general and also the delay in diagnosis from a preexisting tumor. We report a case of PNF of face involving oral cavity with literature review.
