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.
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 .
Adrenal glands, anterior (left) and posterior (right) surface. The adrenal glands are located on both sides of the body in the retroperitoneum, above and slightly medial to the kidneys. In humans, the right adrenal gland is pyramidal in shape, whereas the left is semilunar or crescent shaped and somewhat larger. [8]
Primary pigmented nodular adrenocortical disease (PPNAD) was first coined in 1984 by Carney et al. it often occurs in association with Carney complex (CNC). CNC is a rare syndrome that involves the formation of abnormal tumours that cause endocrine hyperactivity.
Adrenal gland disorders (or diseases) are conditions that interfere with the normal functioning of the adrenal glands. [1] Your body produces too much or too little of one or more hormones when you have an adrenal gland dysfunction. The type of issue you have and the degree to which it affects your body's hormone levels determine the symptoms.
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.
Very rarely, they may become cancer if left untreated for a long time or if they are not completely removed and grow back. It's not clear exactly how benign tumors become cancers. There are many types of salivary gland cancers. Normal salivary glands are made up of several different types of cells, and tumors can start in any of these cell types.
Direct compression of adrenal glands and acute intravenous pressure rise due to compression of the inferior vena cava are the two proposed mechanisms of traumatic adrenal gland injury. [ 1 ] Non-traumatic adrenal hemorrhage is an atypical type, which can be further categorised as acute stress and neonatal stress, anti-phospholipid antibody ...
