Peripherin

Peripherin is a type III intermediate filament present is cells derived from the neural tube and neural crest.

Immunohistochemical expression

• neurones

• b cells of pancreatic islets2

• some neuroendocrine tumours:

  • neuroblastoma4

  • ganglioneuroblastoma

  • Merkel cell carcinoma3
