A silver colloid technique to demonstrate nucleolar organizer region-associated proteins (AgNORs) was performed on sections of 39 human adrenal glands, including normal adrenal cortex, bilateral adrenocortical hyperplasia, adenoma, and carcinoma. In mineralocorticoid and glucocorticoid-producing adrenocortical cells, the mean number of AgNORs per nucleus was lowest in the normal adrenal gland and highest in adenoma, with statistically significant differences. The mean number of AgNORs in bilateral adrenocortical hyperplasia was placed between that of normal adrenal and adenoma. AgNOR numbers in morphologically and clinically verified adrenocortical carcinoma (12 cases) were not different from those in adenoma (17 cases). In adrenal cortex, AgNOR numbers may be correlated with increased steroid hormone production but appear to be of little value in discerning malignancy in adrenocortical neoplasms.

UI	MeSH Term	Description	Entries
D006965	Hyperplasia	An increase in the number of cells in a tissue or organ without tumor formation. It differs from HYPERTROPHY, which is an increase in bulk without an increase in the number of cells.	Hyperplasias

D002277	Carcinoma	A malignant neoplasm made up of epithelial cells tending to infiltrate the surrounding tissues and give rise to metastases. It is a histological type of neoplasm and not a synonym for "cancer."

D012834	Silver	An element with the atomic symbol Ag, atomic number 47, and atomic weight 107.87. It is a soft metal that is used medically in surgical instruments, dental prostheses, and alloys. Long-continued use of silver salts can lead to a form of poisoning known as ARGYRIA.
