Cervical lymphadenopathy refers to lymphadenopathy of the cervical lymph nodes (the glands in the neck). The term lymphadenopathy strictly speaking refers to disease of the lymph nodes,[1] often however the term refers to enlargement of the lymph nodes. Similarly, the term lymphadenitis refers to inflammation of a lymph node, but often it is used as a synonym of lymphadenopathy.

In this article, lymphadenopathy is defined as lymph node enlargement, and only causes of neck lumps related to lymph nodes are discussed, as there are many other causes of lumps in the neck.

Cervical lymphadenopathy is a sign or a symptom, not a diagnosis. The causes are varied, and may be inflammatory, degenerative, or neoplastic.[2] In adults, healthy lymph nodes can be palpable (able to be felt), in the axilla, neck and groin.[3] In children up to the age of 12 cervical nodes up to 1 cm in size may be palpable and this may not signify any disease.[4] If nodes heal by resolution or scarring after being inflamed, they may remain palpable thereafter.[1] In children, most palpable cervical lymphadenopathy is reactive or infective. In individuals over the age of 50, metastatic enlargement from cancers (most commonly squamous cell carcinomas) of the aerodigestive tract should be considered.[1]


Cervical lymphadenopathy can be thought of as local where only the cervical lymph nodes are affected, or general where all the lymph nodes of the body are affected.

Lymph nodes may become enlarged in malignant disease. This cervical lymphadenopathy may be reactive or metastatic.[1] Alternatively, enlarged lymph nodes may represent a primary malignancy of the lymphatic system itself, such as lymphoma (both Hodgkin's and non-Hodgkin's),[6] lymphocytic leukemia,[1]

Metastatic lymph nodes are enlarged because tumor cells have detached from the primary tumor and started growing in the lymph node ("seeded"). Since cancer generally occurs more frequently in older people, this kind of lymphadenopathy is more common in older persons.[7] Metastatic lymph nodes tend to feel hard and may be fixed to underlying tissues and may or may not be tender.[7] Usually the lymph nodes that directly drain the area of the cancer are affected by the spread, e.g. Sometimes metastatic cervical lymph node is detected before the main cancer. In such cases, this discovery leads to a search for the primary malignancy, firstly in the nearby area with endoscopy, "blind" biopsies, and tonsillectomy on the side of the lymphadenopathy. If no tumor is found, then the rest of the body is examined, looking for lung cancer or other possible sites. If still no primary tumor is detected, the term "occult primary" is used.[8]

In lymphoma, usually there are multiple enlarged nodes which feel rubbery to palpation.[8]
