This book offers an update about peripheral nerve sheath tumors (PNST), both in their benign and malignant forms (MPNST). Starting from the most innovative preclinical studies about genetic and omics characterization, it then explores the traditional and advanced imaging modalities (ultrasound, DTI, etc) and the electrophysiological assessment. Another relevant part is reserved to the description of the most recent surgical techniques (fluorescent dye for intraoperative surgical guidance, neurophysiological monitoring, esoscopic view). Finally, new oral treatment for PNST related to neurocutaneous diseases (as selumetinib in plexiform neurofibromas) is described. Written by worldwide experts in each specifical field, if offers a multidisciplinary vision to PNST, approaching the topic in a translational way, from preclinical studies to the current medical practice. The ideal readers are all health operators involved in the treatment of these tumors- from neurosurgeons to radiologists, neurologists, geneticists, biologists, etc) as well as medical students in these disciplines.
