Abstract:
Objective To study the characteristic of chromogranin A(CgA),synaptophysin(SYN) and neuron-specific enolase(NSE) in cortex and medulla of adrenal.Methods Immunohistochemical method was used to detect the expression of CgA,SYN and NSE in routinely processed tissue specimens from human adrenal neoplasm and hyperplasia.Results The expression of CgA was detected in cortex of adrenocortical adenoma,adrenal neoplasm and chromophile tumor,but not in that of hyperplasia and normal adrenal.The expression of NSE was detected in cortex of adrenal cortical hyperplasia,cortical adenomas and pheochromocyte carcinoma,but not in that of pheochromocytoma and normal adrenal.The expression of SYN was detected in cortex of corticohyperplassia,cortical adenomas,medull neoplasm,chromophile tumor and pheochromocyte carcinoma,but not in that of cortical adenocarcinoma and normal adrenal.The expressions of CgA,NSE and SYN were detected in the medulla of all cases.Conclusion The characteristic of CgA,SYN and NSE in cortex and medulla of adrenal are useful in the differential diagnosis of tumor and hyperplasia in the adrenal.The relationship between the adrenal cortex and medulla is close.Besides the classical hypothalamus-pituitary-adrenal axis(HPAA) and rennin-angiotensin-aldosterone system(RAAS),the adrenal cortex and medulla have the basis of anatomy and endocrinology.
