Brief Summary
Background:
- Plexiform neurofibromas in patients with NF1 are a significant cause of morbidity but little is known about the natural history of these lesions. Objectives:
- The purpose of this study is to monitor the natural history of plexiform neurofibromas and to evaluate the usefulness of volumetric MRI tumor measurements in this disease.
- Other goals of the study are to provide a body of normative data on the growth rate of plexiform neurofibromas and to establish a tissue repository and pathology review center to allow future studies of the pathogenesis of neurofibromas and clinical trials of potential therapeutic agents. Design \- This study is coordinated by Dr. Bruce Korf, and was initiated when he was at the Partners Center for Human Genetics, Boston, MA.

Eligibility Criteria
A total of 300 plexiform neurofibromas will be studied, consisting of 100 tumors in the head/neck and trunk/limbs (externally visible and internal)
You may not qualify if:
- Presence of metallic implant(s) that will make the patient unable to have MRI studies
- Presence of medical or psychological condition that will make the patient unable to tolerate MRI studies or anesthesia (if needed)
- Inability to image tumor or define tumor margins by MRI (which may be determined after the initial study)
- Failure to obtain initial MRI within 60 days of enrollment
- Previous radiation therapy to site of plexiform neurofibroma
- Surgery involving the plexiform neurofibroma (excluding biopsy) within a six month period before enrollment
- Current antineoplastic therapy
- Entry of more than one member of the same family into the study is not permitted
