Adrenal tumors
The classification of adrenal tumors can be divided into benign tumors and malignant tumors according to their nature; divided into non-functional tumors and functional tumors according to whether they have endocrine function (such as causing hypertension by secreting a certain hormone); and divided into cortical tumors, medullary tumors, stromal tumors, or metastatic tumors according to the site of occurrence. Clinically, adrenal tumors that require surgical intervention are usually functional tumors or highly suspected to be malignant (or difficult to distinguish between benign and malignant before surgery).
The adrenal glands are an important endocrine organ in the body. Due to their close relationship with the kidneys, they have traditionally been classified as urological diseases. There is one adrenal gland on each side of the human body, located retroperitoneally, and its lateral side is closely adjacent to the upper medial side of both kidneys. The shape and size of the adrenal glands look like the slightly bent last finger of an adult at first glance, and the head, body, and tail of the three parts are also like the last finger from the root to the tip. However, if you look carefully, the right adrenal gland is triangular, and the left adrenal gland is crescent-shaped. The former crosses the right pole of the kidney medially, and the latter hangs down from the left pole of the kidney medially. Their lengths, widths, and thicknesses are 4.0 cm to 6.0 cm, 2.0 cm to 3.0 cm, and 0.3 cm to 0.6 cm, respectively. The normal weight of the adrenal glands is about 4.0 to 5.0 grams.
