Metastasis to one or both adrenal glands is the most common form of malignant adrenal lesion, and the second most common adrenal tumor after benign adenomas. [4] Primary tumors in such cases are most commonly from lung cancer (39%), breast cancer (35%), malignant melanoma, gastrointestinal tract cancer, pancreas cancer, and renal cancer. [4]
Adrenocortical carcinoma (ACC) is an aggressive cancer originating in the cortex (steroid hormone-producing tissue) of the adrenal gland.. Adrenocortical carcinoma is remarkable for the many hormonal syndromes that can occur in patients with steroid hormone-producing ("functional") tumors, including Cushing's syndrome, Conn syndrome, virilization, and feminization.
Adrenal gland; the medulla (center, red) is the origin of the pheochromocytoma. There is an adrenal gland, highlighted in yellow, on top of each of the kidneys. Other clinical manifestations that have been reported include (in no particular order): [6] [13] Pallor; Heat intolerance; Weight loss; Chest and/or abdominal discomfort; Palpitations ...
The kidneys are easily examined, and most pathological changes in the kidneys are distinguishable with ultrasound. US is an accessible, versatile inexpensive and fast aid for decision-making in patients with renal symptoms and for guidance in renal intervention. [1] Renal ultrasound (US) is a common examination, which has been performed for ...
This specific characteristic in adenomatoid tumors is variable and can determine whether or not ultrasound is the right technique for the job. [11] Having other options available to identify the tumor helps fill in the gap when ultrasound is not possible. MRI and CT imaging are usually helpful when scanning the adrenal gland for tumors. [12]

The organ of Zuckerkandl is of pathological significance in the adult as a common extra-adrenal site of pheochromocytoma though the most common extra-adrenal site is in the superior para-aortic region between the diaphragm and lower renal poles. [9] Extra-adrenal tumors account for around 25% of all cases of pheochromocytoma. [10]
Additionally, adrenal tumors that are larger than 4 centimeters in size, regardless of whether they produce hormones, also require adrenalectomy due to increased risk of adrenal cancer. Rarely (5–12%), the adrenal tumor may be cancerous (adrenocortical carcinoma), requiring adrenalectomy. Rarer still, the mass may be a metastatic cancer that ...
