Abstract:
We report a rare case of adrenocortical carcinoma. A 26-year-old woman presented with hypokalemia and hypertension due to hyperaldosteronism. She had no signs of Cushing's syndrome. Endocrinological data showed excess of aldosterone production and nonsupressible cortisol production on 2 mg of dexamethasone. Magnetic resonance imaging showed left adrenal tumor. Transabdominal left adrenalectomy was performed and histopathological diagnosis was adrenocortical carcinoma. Her blood pressure and hypokalemia returned to normal after adrenalectomy. There is no recurrence after 36 months. We want to emphasis the importance of adrenal tests before the operation even if there are no signs of excess cortisol production.

Cushing Syndrome II: Pathophysiology
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...
Cushing Syndrome I: Introduction
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...
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.
The adrenal gland comprises two distinct regions...
