There are three major clinically and genetically distinct forms of neurofibromatosis: neurofibromatosis types 1 and 2 (NF1 and NF2) and schwannomatosis. NF1, also known as von Recklinghausen disease, is the most common type. The hallmarks of NF1 are the multiple café-au-lait macules and neurofibromas. The condition is called segmental NF1 when clinical features are limited to one area of the body. Neurofibromatosis affects an estimated 100,000 people in the U.S., occurring in all ethnic groups. l
Surgery to remove the entire tumor while it’s still small might help preserve hearing. If hearing is lost during this surgery, but the auditory nerve is maintained, the surgical placement of a cochlear implant (a device placed in the inner ear, or cochlea, that processes electronic signals from sound waves to the auditory nerve) may be an option to improve hearing. Soft-tissue sarcomas, which result in approximately 10,700 diagnoses and 3,800 deaths per year in the United States1, show remarkable histologic diversity, with more than 50 recognized subtypes2. However, knowledge of their genomic alterations is limited.
