Where is the epitrochlear lymph node located?

The epitrochlear lymph node is specifically located in the elbow region, positioned above the medial epicondyle of the humerus, which is the inner part of the elbow joint. These lymph nodes are part of the immune system, playing a crucial role in filtering lymphatic fluid and participating in the body’s immune response. They are especially associated with drainage from the hand and forearm.

In comparison to the other regions mentioned, the chest contains other lymph nodes such as the mediastinal lymph nodes, the groin has inguinal lymph nodes, and the neck houses cervical lymph nodes. None of these are involved with the epitrochlear lymph nodes, making the elbow region the correct and precise location for these particular lymph nodes.
