Summary
This study reports the largest benign adrenal cortex adenoma ever documented, measuring 32 cm and weighing 7,500g. This rare giant adrenal tumor highlights the potential for benign growths to reach extraordinary sizes.
Area of Science:
- Endocrinology
- Surgical Oncology
- Pathology
Background:
- Adrenal cortex adenomas are common endocrine tumors.
- Larger adrenal tumors (>4 cm) are often malignant, while giant adenomas (>20 cm) are exceptionally rare.
- Non-functional adenomas are typically asymptomatic and discovered incidentally.
Purpose of the Study:
- To present a rare case of a non-functional giant benign adrenal adenoma.
- To document the largest benign adrenal cortex tumor reported in the literature.
Main Methods:
- Surgical resection of the adrenal tumor.
- Detailed measurement of the resected tumor's dimensions and weight.
- Comprehensive literature review to compare with existing cases.
Main Results:
- A non-functional giant benign adrenal adenoma measuring 32 cm in diameter and weighing 7,500 g was successfully resected.
- Literature search confirmed this as the largest benign adrenal cortex tumor reported to date.
Conclusions:
- Giant benign adrenal adenomas, though rare, can reach unprecedented sizes.
- This case underscores the importance of surgical intervention for large adrenal masses, even when non-functional.

01:27Adrenal Gland Disorders
Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
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...

01:26Cushing Syndrome I: Introduction
Cushing syndrome refers to the collection of clinical manifestations that arise when tissues are exposed to excessive amounts of cortisol or cortisol-like medications over an extended period. Cortisol, a glucocorticoid produced by the adrenal cortex, regulates metabolism, immune responses, and the body’s adaptation to stress. When its concentration remains chronically elevated, these physiological pathways become dysregulated, resulting in the characteristic features of the syndrome.Exogenous...
01:19Cushing Syndrome II: Pathophysiology
Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features of the...
01:17Anatomy of the Adrenal Glands
The adrenal or supra-renal glands, situated above the kidneys and aligned with the twelfth rib, are paired pyramid-shaped structures crucial for the body's stress response. During stress, these glands secrete hormones vital for adaptive physiological reactions.
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...

01:31Hormones of the Adrenal Glands
Adrenal hormones play a pivotal role in maintaining the body's electrolyte balance and orchestrating responses to stress, showcasing the intricate functions of the adrenal cortex and medulla.
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...

01:27Goiter
Goiter refers to an abnormal enlargement of the thyroid gland that may appear as a diffuse goiter (uniform enlargement) or nodular (single or multiple nodules). Functionally, it is classified as nontoxic (normal/low hormone levels) or toxic (excess hormone production).PathophysiologyDiffuse thyroid enlargement typically results from prolonged stimulation by thyroid-stimulating hormone (TSH) or TSH-like agents, commonly seen in hypothyroidism or iodine deficiency. In contrast, in hyperthyroid...
