Where are the epitrochlear lymph nodes located?
The epitrochlear nodes are located in the subcutaneous connective tissue on the medial aspect of the elbow, about 4–5 cm above the humeral epitrochlea.
Where does the lymphatic drainage originate?
As a general rule, the epitrochlear station drains the lymph from the last two or three fingers and from the medial aspect of the hand itself. Nevertheless, drainage areas of the upper limb are characterized by wide interindividual variability. Some lymphatic vessels arise from the epitrochlear nodes and extend to the axillary station [1](Fig. 1).
What causes swelling in the medial elbow?
Swelling, particularly when it involves the medial aspect of the elbow, may have a variety of nodal and extranodal causes. The former group includes acute lymphadenitis (cutaneous infections, cat-scratch disease, etc.), tubercular lymphadenitis, sarcoidosis-related lymphadenitis, lymphomas, and metastatic lymphadenopathies (chiefly from melanomas, but also from other cutaneous and noncutaneous tumors) (Figs. 2 and 3). Among the extranodal causes of elbow swelling are tumors (median nerve tumors, fibromas, hemangiomas, lipomas, and Merkel cells tumor), sebaceous cysts, abscesses (septic arthritis of the elbow joint), Kimura disease, cutaneous and subcutaneous hematogenous metastases [6,7].
Is the axilla the primary lymphatic target?

The focus of this pictorial review is to illustrate, through a number of paradigmatic cases, the normal and abnormal findings that can be demonstrated with US and color-Doppler US in studies of the epitrochlear lymph nodes and in the general work-up of elbow masses. Informed consent to this report was obtained from all patients.

Why is the size of a lymph node important?
Hence, we can say that the size of a lymph node plays a very important role in determining various medical conditions. This is the reason why a health care specialist checks for any swollen nodes in the major locations such as neck, armpit, collarbone, and groin during physical examination.
What is the function of lymph nodes?
Lymph nodes are small, bean-shaped organs of the lymphatic system. The lymphatic system circulates the interstitial fluid called lymph to the body cells and tissues. It also collects waste substances from the bloodstream.
What is the role of lymph nodes in autoimmune disease?
Lymph nodes contain lymphocytes, which is a type of WBC. At the time of infection, in response to the antigen, lymphocytes make antibodies which target the pathogens and destroy them. Due to this activity, there is an increase in the production of beta cells which results in swollen, inflamed, painful and sensitive nodes. Significant change in their size can be observed during mild infection like cold and life-threatening condition like cancer.

What is the biopsy of lymph nodes?
A biopsy requires the removal of the lymph node. The sentinel node is frequently removed to minimize the number of nodes for the biopsy. Studies indicate that if cancer cells are not found in the sentinel node, it has not spread to other parts of the body. Every surgery has possible risk and complications but operations that are distinct from the removal of the lymph nodes include the following: 1 Weakened immune system 2 Seroma – a buildup of lymph fluid in the area 3 Lymphedema – lymph fluid collection in limbs
What causes lymph nodes to swell up?

The swollen nodes can sometimes be felt along the jaw line, under the arm, or in the groin area. Typically the swelling will be closest to the part of the body with the infection. For example, if you have the flu, the nodes of your neck may be tender and swollen. Doctors will often feel a patient's neck and jawline to look for this swelling as an indication of infection. Lymph nodes will feel like round lumps under the skin.
What is the fluid that travels through the lymph nodes?
Lymph contains extra fluids that are drained from cells and tissues and travel throughout the lymphatic system via a network of lymphatic vessels. When lymphatic fluid travels through the lymph nodes, foreign bodies such as viruses and bacteria are trapped and then destroyed by lymphocytes, a type of white blood cell.
What are the four main layers of lymph nodes?
These bean-shaped structures are composed of four main layers - the capsule, subscapular sinus, cortex, and medulla. The capsule is the outermost layer of the lymph node and is made of connective tissue and fibers.

Where are the lymph nodes located in the thorax?
Thoracic lymph nodes are separated into two types: parietal lymph nodes located in the thoracic wall, and visceral lymph nodes, which are associated with the internal organs. Due to their location, abnormalities of the lymph nodes in the thorax, or chest, are not easily detected. However, any changes in the size or amount of these lymph nodes could be indicative of several types of extrapulmonary or pulmonary diseases. For diagnostic purposes, lymph nodes of the thorax can be further divided into sub-categories. The lung lymph nodes can be found along the bronchi. The paratracheal and tracheobronchial groups of lymph nodes are located in the neck and also in the junction where the trachea meets the bronchi, respectively. These accept drainage from the heart, lungs, bronchi, and thoracic trachea as well as other lymph nodes. The posterior mediastinal group of lymph nodes, located near the thoracic aorta, is closely linked to the tracheobronchial group and primarily drains into the thoracic duct. The chest wall thoracic lymph nodes receive drainage from the breasts, arms, pectoral muscles, and other muscles and skin located in the upper section of the chest.
