The nodes themselves may be tender or non-tender, fixed or mobile, discreet or "matted" together. Concomitant symptomatology and the epidemiology of the patient and the illness provide further diagnostic cues. Lymph nodes are distributed in discrete anatomical areas, and their enlargement reflects the lymphatic drainage of their location. Localized adenopathy occurs in contiguous groupings of lymph nodes. Generalized lymphadenopathy entails lymphadenopathy in 2 or more non-contiguous locations. Lymphadenopathy occurs in 2 patterns: generalized and localized. The pattern, distribution, and quality of the lymphadenopathy can provide much clinical information in the diagnostic process. However, an epitrochlear node of above 0.5 cm is deemed to be pathological in an adult. For example, children younger than ten have more hypertrophic immune systems, and nodes up to 2 cm can be considered normal in some clinical situations. However, the reality is that "normal" and "enlarged" criteria vary depending on the location of the node and the age of the patient. It is generally held that a node size is considered enlarged when it is more significant than 1 cm. In this reaction, there is some multiplication of the responding resistant cell line, and thus, the node itself increases in size. In this way, the immune system can recognize and react to foreign proteins and mount an immune response or sequester these proteins as appropriate. It consists of a multi-layered sinus that sequentially exposes B-cell lymphocytes, T-cell lymphocytes, and macrophages to an afferent extracellular fluid. The lymph node functions as an antigen filter for the reticuloendothelial (RE) system of the body. A clear understanding of lymph node function, location, description, and the etiologies of their enlargement is important in the clinical decisions of which cases need rapid and aggressive workup and which need only be observed. However, it is generally recognized that most lymphadenopathy, both localized and generalized, is of benign, self-limited etiology. Patients and physicians have varying degrees of associated anxiety with the finding of lymphadenopathy as a small number of cases can be caused by neoplasm or infections of consequence, for example, HIV or tuberculosis (TB). More often than not, swollen lymph nodes are just part and parcel of the lymphatic system doing its job.Lymphadenopathy is a common abnormal finding during the physical exam in general medical practice. It may also indicate cancer, but this is far less common. Lymphadenopathy can also occur in the lymph nodes located inside the chest and abdominal cavities.Ĭervical lymph node swelling can be a reliable indicator of infection or other inflammation in the area. Other sites where lymph nodes commonly swell include the underarm and groin. This is because the infection near the neck is filtered through the lymph nodes in the neck, which leads to swelling. Since lymphadenopathy tends to occur in one area of nodes at a time, it’s common for infections in or around the neck to trigger cervical lymph swelling. Many things can cause cervical lymph node swelling, including: Generally, swollen cervical lymph nodes are nonthreatening. ![]() It can occur in reaction to infection, injury, or cancer. This common occurrence is referred to as lymphadenopathy. Sometimes the lymph nodes in your neck, as well as other parts of your body, can swell. What causes swollen cervical lymph nodes?
