Open full text 0 citations

Abstract

Malignant peripheral nerve sheath tumor (MPNST) is one of the soft tissue sarcoma believed to originate from neural crest cells. The patients with neurofibromatosis type I (NF1) have about 8-13% of the lifetime risk of the malignant transformation. Neurofibroma on patients with NF1 can be surgically resected and has good prognosis if approach to the tumor is possible. We experienced a case of a 50-year-old woman with NF who had incompletely resected neurofibroma, which presented a rapid malignant transformation to MPNST, 3 months after the first surgery. We reported this case with a brief review of literature.
