Abstract:
We present the first case of a nonmetastasizing renal cell carcinoma (RCC) masquerading as an adrenal mass, in the presence of normal bilateral native kidneys, in a young adult. The possibility of this mass developing in a supernumerary kidney was ruled out, since no identifiable renal tissue, pelvis or ureters was seen within the mass, nor was any separate systemic arterial supply to the mass seen. The diagnosis of extra-renal clear cell RCC was based on cyto-morphological features, further confirmed by immunohistochemistry findings. The origin of this extra-renal clear cell renal cell is proposed to be from the mesodermal embryonic rests.

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...
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...
External Anatomy of the Kidney
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
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...
