Furthermore, the endoneurium of perineurioma lacks an abundant mucinous matrix.
6) More recently, investigators have proposed that malignant cells invade and spread via potential spaces in the connective tissue planes of the perineurium and endoneurium without inciting an inflammatory response in the surrounding stroma or invading the nerve fibers themselves.

2,3) Normal perineurial cells constitute the perineurium, a protective barrier situated between the epineurium and endoneurium layers of the nerves that surround both myelinated and unmyelinated axon-Schwann cell complexes of peripheral nerve fascicles.
Invasion of the endoneurium may follow, and the whole endoneurial zone may appear to be occupied by epitheloid cells with or without the presence of bacilli.
Each fiber or group of fibers is enveloped by endoneurium, a loose collagenous matrix that protects and nourishes each axon.
