The purpose of the research study is intended to use specimens (such as tissue) and medical information in the Laboratory of Musculoskeletal Oncology at the Van Andel Research Institute for laboratory research in Grand Rapids, Michigan. Small tissue samples of cutaneous neurofibromas will be collected as part of this research. The samples will help researchers learn more about cutaneous neurofibroma and help them better understand NF1. There are many different types of studies, both now and in the future, that can be done using the specimens the investigators receive. These include using the specimens and information to look for new ways to diagnose and treat Neurofibromatosis Type 1 (NF1). The specimens may be used to study how genes affect health and disease, or how genes affect the way a disease or condition responds to treatment. Some of these studies may lead to new products, such as treatments or tests for diseases. Through this study, the investigators hope to find better ways to understand and treat NF1 in the future.
