"Another acceptable term of hybrid nerve sheath tumour is ‘benign nerve sheath tumour NOS’."
"Hybrid nerve sheath tumours are generally rare and tumours showing a hybrid morphology of schwannoma/perineurioma or neurofibroma/schwannoma are more common than the neurofibroma/perineurioma hybrid. They have been found in a wide age range but seem to have a peak in young adults. There is apparently no gender predilection 1-3."

"Schwann cells generally react to S100, perineurial areas usually demonstrate positivity for epithelial membrane antigen (EMA), claudin 1 or Glut1 but not S100, whereas neurofibromatous components display a mixed picture of CD34, S100, SOX10, and EMA positivity 1-3."
