Story of the case: C.H.V.D, 18 years, masculine, recent diagnosis of NF1, directed to the service of Surgery of Head and Neck of the Santa Casa of Belo Horizonte with story of right cervical mass has 2 years, presenting growth fast e local pain in last the 3 months.

It was submitted to the surgical resection of the tumor that included segment of the vacant nerve. Pathological anatomo evidenced fusocellular neoplasias with peripheral, atypia areas of plexiform standard and has taken free increase of the cellularity, edges. The patient meets in ambulatorialy accompaniment has 6 months without return signals. CONCLUSION: the risk of malignant transformation of one neurofibrome in patient with NF1 is of 8 13%. The cervical region is the place less common for the development of Malignant Neoplasia of Case of Peripheral Nerve. Malignant degeneration of neurofibrome vagal is extremely uncommon.
