adrenal glands perform complex and very important functions in the human body and have a fairly complex structure.In fact, they are endocrine glands responsible for hormone synthesis and metabolism.In structure formed from the outer adrenal glands, and cerebral cortical layers.
for the synthesis of steroid hormones, adrenal cortex responds by taking part in the development of secondary sexual characteristics in water-salt and protein and carbohydrate metabolism.
In the case of tumor destruction of one of the layers of the adrenal glands develop appropriate endocrine disease, with ourselves tumors can be either benign or malignant and manifest itself in different ways, depending on their nature and location.If you have adrenal tumors require prompt medical intervention.
to its location the tumor divided into two very different types, it is a tumor of the adrenal medulla and the cortex of the tumor.In this view both the tumor can be either benign or malignant.
Regarding adrenal benign tumors, they mos
Like all cancers, malignant neoplasm of adrenal divided into primary and secondary.The first type is a tumor derived from the adrenal tissue itself, and the second are metastases of cancers of other organs of the human body.
Consider the primary tumor.It is said that this type of tumors in the adrenal glands can refer either to the tumor, producing a large amount of some hormone that makes them hormonally active or to hormonally inactive tumors such intsedentalomy.
Most of hormonally inactive tumors are benign, such as myoma, lipoma and fibroma.However, there are malignant tumors of hormonally inactive, but they occur much less frequently.Such tumors include, for example, pyrogenic cancer, melanoma and teratoma.
symptoms of hormonal adrenal tumors
tumor that produces excess hormone aldosterone, which is responsible for the mineral-salt metabolism in the human body, called aldosteronoma.With the development of this type of adrenal tumors occur symptoms such as muscle weakness, hypokalemia, hypertension, and alkalosis.At this moment only 2 - 4% aldosteroma patients are malignant.
increased production of the hormone glucocorticoid leads to the development of the syndrome of Cushing.This swelling is called - glyukosteroma.Patients observed hypertension in adults occurs early extinction of sexual function in children - early puberty, as well as obesity.This type of tumor is most common and can have as a malignancy, for example, and kortikoblastomy adenocarcinoma and benign, e.g., adenoma.
One of the most rare and most of malignant tumors is kortikoesteroma whereby estrogen produced.In such patients develop tumors in estrogen-genital syndrome that causes impotence in men and feminization.
Androgen-genital syndrome develops when androsterome, tumor producing androgens.50% of these tumors are malignant and tend to metastasize to the retroperitoneal lymph nodes, liver and lungs.Most susceptible androsteromam women aged 20 - 40 years.
This type of tumor of the adrenal glands as pheochromocytoma is accompanied by autonomic crises and in most cases are benign.Only 10% of cases the tumor becomes malignant, the most vulnerable to its occurrence in women aged 30 - 50 years.
Symptoms hormonally inactive adrenal tumors
Hormone-inactive adrenal tumors usually have a very small size and do not show any symptoms themselves.Can not find them by chance during the passage of the patient studies such as CT scans, ultrasound and MRI in the diagnosis assigned completely different diseases.
I must say that although this type of cancer and is considered hormonally inactive, yet when it appeared like a very small tumors exhibit hormonal activity.However, she so small that does not cause any visible symptoms.
for the diagnosis of these tumors is conducted urine for the content of catecholamines, free cortisol, aldosterone, as well as homovanillic acid and vanillylmandelic.In exceptional cases, in addition appointed selective adrenal venography.
