'''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 onetwo know survivors over this age,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>. the other know survivor a South African man (34) had 7 PNET tumours in his neck in 2002.

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".
