Para confirmar que la neoplasia deriva de las celulas de Schwann, se evaluaron los siguientes marcadores: neurofilamento
Schwannomas are usually benign tumors arising from Schwann cells of the peripheral nerve sheath (1).
During the fourth week of embryological development these Schwann cells are derived from a specialized population of ectomesenchymal cells of the neural crest.
Proliferating Schwann cells of peripheral nerve sheaths form Schwannoma (or neurilemmoma).
6) On CT scan, a PNST appears as a well-defined mass that is hypodense compared with muscle because of the presence of Schwann cells, neural elements, and adipocytes.
On immunohistochemical analysis, capsule stains for EMA, and Schwann cells stain for S-100, collagen type IV and vimentin.
In the present study, we examined the localization of DCUN1D2 and NEDD8 in the sciatic nerves, and found that these neddylation-related molecules were present mainly in the myelin paranodal regions and Schwann cell bodies.
On the other hand, Schwann cells in the PNS are best known for their roles in supporting nerve regeneration, conducting nerve impulses along axons, and modulating neuromuscular synaptic activity and nerve development [85].
The schwanoma and neurofibroma differ histologically and histogenetically; the schwannoma is derived from the Schwann cells and the neurofibroma from the fibroblasts of the perineurium.
3) It is thought that GCT neoplasms are of neural origin, as many have histologic and protein expression characteristics similar to Schwann cells in the peripheral nervous system.
In our study we selected the nerve samples of HNPP patients because of reversible clinical symptoms and distinct pathological findings with the focal enlargement of myelin sheath called "tomaculas" and scattered onion bulb structures and Schwann cells proliferation (15).
