Summary
Adrenocortical oncocytoma, a rare adrenal tumor, is typically benign. This study details a large, 20 cm oncocytic adrenocortical tumor with uncertain malignant potential found after resection.
Area of Science:
- Endocrinology
- Oncology
- Pathology
Background:
- Oncocytomas are neoplasms composed of oncocytes, commonly found in salivary glands, kidneys, and thyroid.
- Adrenocortical oncocytomas are rare and usually present as benign, nonfunctioning tumors.
- Large adrenal masses require careful evaluation due to potential for malignancy.
Purpose of the Study:
- To report a rare case of a large oncocytic adrenocortical tumor.
- To describe the histopathological findings and uncertain malignant potential of the tumor.
- To contribute to the understanding of rare adrenal neoplasms.
Main Methods:
- Surgical resection of a 20 cm adrenal mass.
- Histopathological evaluation of the resected tumor.
- Analysis of tumor characteristics including size, necrosis, and cellular morphology.
Main Results:
- A 20 cm adrenal mass was resected.
- Histopathological examination identified the mass as an oncocytic adrenocortical tumor.
- The tumor exhibited necrosis and uncertain malignant potential.
Conclusions:
- Large oncocytic adrenocortical tumors, though rare, can present with features of uncertain malignant potential.
- Comprehensive histopathological evaluation is crucial for diagnosing and assessing the risk of adrenocortical tumors.
- Further research is needed to clarify the behavior and management of oncocytic adrenocortical tumors.

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...
01:27Adrenal 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...
01:33Cancer-Critical Genes I: Proto-oncogenes
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

02:23Abnormal Proliferation
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
