Objective:
To report a case of left adrenocortical neoplasm.
Methods:
A case of left adrenocortical neoplasm measuring 16 x 10 x 7 cm in a 47-year-old male is presented. After puncture biopsy, a left adrenalectomy through the abdominal approach was performed.
Results:
Immunohistochemical studies showed reactivity to the anti-Melan-A A103 antibody, suggesting an adrenal origin of the tumor cells. Strong reactivity to the mES-13 mitochondrial antibody, which is characteristic of oncocytes, made ultrastructural studies unnecessary.
Conclusions:
In this type of tumor, an increased mitotic activity and necrosis are suggestive of malignancy. Despite the foregoing, most of this type of lesions are clinically benign and nonfunctioning.

Sympathetic Pathways: Collateral Ganglia and Adrenal Medulla
Collateral Ganglia
Sympathetic preganglionic axons reach the collateral ganglia along the route of splanchnic nerves. These nerves bypass the sympathetic trunk and communicate with sympathetic postganglionic neurons housed in the prevertebral ganglia. These ganglia supply the organs of the abdominopelvic cavity.
The greater splanchnic nerve, formed by the...
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...
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...
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.
