'''Primitive neuroectodermal tumor''' (PNET) is a malignant (cancerous) [[neural crest]] tumor.<ref>{{DorlandsDict|eight/000112249|primitive neuroectodermal tumor}}</ref> It is a rare [[tumor]], usually occurring in children and young adults under 25 years of age. The overall 5 year survival rate is about 53%. The survivor rate drops drastically over 25 to .006. To date there is only one 5 year survivor at 48 years of age. The 48 year old survivors tumor was found entangled in the cervical spinal cord specifically number 3 and 4. <ref name=Smoll20111>{{cite doi|10.1002/cncr.26387}}</ref>

It gets its name because the majority of the cells in the tumor are derived from [[neuroectoderm]], but have not developed and differentiated in the way a normal [[neuron]] would, and so the cells appear "primitive".
