Abstract:
The ultrastructural features of 30 adrenal cortical carcinomas have been reviewed and compared with those seen in adrenal cortical adenomas, adrenal cortical hyperplasia, and the normal cortex. A broad range of ultrastructural appearances was found among the carcinomas, but the differences were mainly in the amount of cytoplasmic lipid, number of lysosomes, and quantity and architecture of the mitochondria and endoplasmic reticulum. Structural variants among the carcinomas included lipid-rich, oncocytic, and glycogen-rich cells. Electron microscopy can be extremely useful in differential diagnoses that include adrenal cortical carcinoma.

Anatomy of the Adrenal Glands
These glands possess a distinctive yellow tinge due to the stored cholesterol and fatty acids required for hormone synthesis. They are encased in a fibrous capsule and cushioned by fat.

Adrenal Gland Disorders
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...
Hormones of the Adrenal Glands
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and corticosterone...
