RASopathies comprise several genetic syndromes with mainly cardio–facial–cutaneous manifestations. We report a patient with Noonan syndrome with multiple lentigines (NSML) due to a PTPN11 (p.Thr468Met) mutation associated with hypertrophic neuropathy of lumbar plexus in an adult woman, initially referred for neuropathic pain. Differential diagnosis of neurofibromatosis type 1 (NF1) and other RASopathies is difficult without molecular testing. © 2016 Wiley Periodicals, Inc.
