Assessing the Efficacy of Repeat, Monthly Treatments of Deoxycholate for NF1 Associated Cutaneous Neurofibromas (cNFs)

The goal of this clinical trial is to evaluate the tolerability and effectiveness of multiple treatments of an FDA-approved drug in those with Neurofibromatosis Type 1 (NF1) Cutaneous Neurofibromas (cNFs). The main questions it aims to answer are: Will performing: * Up to 6 months treatment sessions * A minimum of 30 days apart * With up to 50 injections of deoxycholate into a maximum of 50 cNFs in a single region of the body (for a maximum total dose of 10 mL per monthly treatment session) result in tolerable local skin reactions and reduction in both individual cNF size by \>50% as well as improved cNF appearance in the treated field? Researchers will compare treated tumors and control tumors to see if the treatment is effective. Participants will: * Receive up to 6 monthly treatments with Kybella (deoxycholate). Treatment for a given tumor will be stopped when the tumor is assessed as clear clinically. * Complete surveys asking about pain during and after treatments. * Complete surveys asking about satisfaction with the treatments. * Undergo 2D photography and 3D imaging of treatment areas. * Optionally, receive biopsies of up to 6 treated lesions to investigate characteristics of tumors that respond well to treatment as well as non-respondent tumors.
