Lymphadenopathy

Lymphadenopathy is the enlargement of one or more lymph nodes, the small structures that are part of the body's defense system. It is usually a response of the body to infections, inflammation, or other conditions.

How it shows up: it may be felt as small lumps or bumps under the skin, especially in the neck, armpits, or groin; at times they are tender to the touch.

Possible causes: infections, immune system reactions, and other situations can explain its appearance; that is why it is advisable to study it.

Which specialist evaluates it? The hematologist studies alterations related to the blood and lymph nodes, and the allergist contributes when an immune component is suspected. If a node enlarges, persists, or changes, it is worth discussing it with a professional to guide the workup.
