An adrenal tumor or adrenal mass[2] is any benign or malignant neoplasms of the adrenal gland, several of which are notable for their tendency to overproduce endocrine hormones. Adrenal cancer is the presence of malignant adrenal tumors, and includes neuroblastoma, adrenocortical carcinoma and some adrenal pheochromocytomas.
Adrenalectomy. Adrenalectomy (Latin root Ad "near/at" + renal "related to the kidneys" + Greek ‑ectomy “out-cutting”; sometimes written as ADX for the procedure or resulting state) [1][2] is the surgical removal of one (unilateral) or both (bilateral) adrenal glands. It is usually done to remove tumors of the adrenal glands that are ...
Myelolipoma (myelo-, from the Ancient Greek μυελός 'marrow'; lipo, 'of, or pertaining to, fat'; -oma 'tumor or mass'; also myolipoma) is a benign tumor-like lesion composed of mature adipose (fat) tissue and haematopoietic (blood-forming) elements in various proportions. [1] Myelolipomas can present in the adrenal gland, [2] or outside of ...
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.
An adrenocortical adenoma or adrenal adenoma is commonly described as a benign neoplasm emerging from the cells that comprise the adrenal cortex. Like most adenomas, the adrenocortical adenoma is considered a benign tumor since the majority of them are non-functioning and asymptomatic. Adrenocortical adenomas are classified as ACTH -independent ...
Pheochromocytoma is a rare tumor of the adrenal medulla composed of chromaffin cells and is part of the paraganglioma (PGL) family of tumors, being defined as an intra-adrenal PGL . [ 2 ][ 4 ][ 5 ] These neuroendocrine tumors can be sympathetic, where they release catecholamines into the bloodstream which cause the most common symptoms ...
Neuroblastoma (NB) is a type of cancer that forms in certain types of nerve tissue. [1] It most frequently starts from one of the adrenal glands but can also develop in the head, neck, chest, abdomen, or spine. [1] Symptoms may include bone pain, a lump in the abdomen, neck, or chest, or a painless bluish lump under the skin.
Incidental adrenal masses on imaging are common (0.6 to 1.3% of all abdominal CT). Differential diagnosis include adenoma, myelolipoma, cyst, lipoma, pheochromocytoma, adrenal cancer, metastatic cancer, hyperplasia, and tuberculosis. [3]
