Immunocytochemical demonstration of CgA and NESP55 in a pancreatic endocrine tumour (EPT, malignant insulinoma), an adrenal pheochromocytoma (PC) and a neuroblastoma (NB). Consecutive sections were stained with an indirect immunoperoxidase technique (EnVision+™). The majority of tumour cells are positive for CgA and NESP55. TH=tyrosine hydroxylase.
