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 secretion of some hormones causing hypertension); and divided into cortical tumors, medullary tumors, stromal tumors, or metastatic tumors according to the occurrence site. Adrenal tumors that require surgical intervention in clinical practice are usually functional tumors or highly suspected malignant tumors (or preoperative inability to distinguish benign and malignant).
The adrenal gland is an important endocrine organ in the body. Due to its close relationship with the kidneys, it is traditionally classified as a urological disease. The human adrenal gland has one on the left and one on the right, located retroperitoneally, and the lateral side is closely adjacent to the upper medial side of both kidneys. The shape and size of the adrenal gland look very similar to the slightly bent end of an adult finger, and the head, body, and tail parts are also like the tip of the finger from the root to the tip. But if you look closely, the right adrenal gland is triangular, and the left adrenal gland is crescent-shaped. The former straddles the inner side of the right renal pole, and the latter hangs from the inner side of the left renal pole. The length, width, and thickness are4.0 cm to6.0 cm,2.0 cm to3.0 cm and 0.3cm to 0.6grams. The normal weight of the adrenal gland is about4.0 to5.0 grams.
Although the adrenal gland itself is very small, the volume of the tumor it grows can vary greatly. Usually, the diameter3cm below are called small tumors, and the smallest are less than1cm, and the larger ones can reach more than30 centimeters. The shape of the tumor can be like beans, peaches, apples, honeydew melon, pillows, etc.
