Marchana Accessory Adrenal Gland

Marchana accessory Adrenal gland

Marchand's accessory adrenal gland (f. J. Marchand, 1846-1928) is an additional formation that is located on the upper border of the adrenal gland and consists of medulla. It was first described by French pathologist François Jean Marchand in 1883.

The adrenal glands are paired endocrine glands that are located above the kidneys and produce hormones that regulate metabolism in the body. They consist of two parts: the cortex and the medulla. The cortex produces the hormones adrenaline and norepinephrine, which are responsible for the body's response to stress and are involved in the regulation of blood pressure. The medulla produces the hormone melatonin, which is involved in the regulation of circadian rhythms and affects sleep.

Marchand discovered that some people have an additional structure on the upper border of the left adrenal gland, which he called the accessory adrenal gland. He described it as a small mass of tissue consisting of the adrenal medulla. Marchand suggested that this formation may be associated with impaired development of the adrenal gland or with other diseases.

Subsequently, many studies were conducted that confirmed that the accessory adrenal gland does exist and can be associated with various diseases. For example, patients with Cushing's syndrome, which is characterized by excess production of adrenal hormones, may have an accessory adrenal gland. It has also been found that the presence of an accessory adrenal gland may be associated with an increased risk of developing adrenal cancer.

Thus, the Marchana accessory adrenal gland is an additional formation on the upper border of the adrenal glands and can be associated with various diseases and developmental disorders. However, despite the fact that its presence may indicate certain health problems, it is not the main diagnostic sign and requires additional examination and consultation with a doctor.

In medical circles, the concept of marchand supplement to the adrenal gland is very widespread. The first mention of this anomalous neoplasm in 1795 is found in the literature. German authors, together with Latvians, described these cases in the journal Acta Pathologica Academiae Scientiarum Вulgariensis. This conglomerate of three endocrine organs, according to most experts, is a cystic dermoid tumor. In 1853, Rütsch in Stuttgart describes the same kind of education. It is typical in children and is called pituitary-visceral duxia, representing the most characteristic pathomorphological picture of mixed pituitary tumors with a visceral source of tissue, characterized by an abundance of vessels in the presence of one or two “adrenal” bundles. Its origin, like the two previous formations, is apparently associated with pathological processes in the embryo and is not associated with the addition of one gland to another. The tumor is common and makes up a significant part of the total mass of cysts of the cerebral appendage. The most noticeable deformities in the area of ​​brain tissue are observed at the connection of the gonad with the brain with a normal clinoid process. The first connective tissue body is noted at about one year of age
