Overview
Lymphadenopathy may be classified according to distribution into 2 groups localized lymphadenopathy and generalized lymphadenopathy.
Classification
Depending upon the involvement of the lymph nodes, lymphadenopathy is classified into 2 groups:[1]
- Localized lymphadenopathy: due to localized spot of infection e.g. an infected spot on the scalp will cause lymph nodes in the neck on that same side to swell up
- Generalized lymphadenopathy: due to generalized infection all over the body e.g. influenza
- Persistent generalized lymphadenopathy (PGL): persisting for a long time, possibly without an apparent cause
- Dermatopathic lymphadenopathy: lymphadenopathy associated with skin disease. Tangier disease (ABCA1 deficiency) may also cause this.
Lymphadenopathy may be classified as follows:
- By location:
- Dermatopathic lymphadenopathy: lymphadenopathy associated with skin disease.
- By malignancy: Benign lymphadenopathy is distinguished from malignant types which mainly refer to lymphomas or lymph node metastasis.
- By extent:
- Localized lymphadenopathy: due to localized spot of infection
- Generalized lymphadenopathy: due to systemic infection of the body. In some cases, it may persist for prolonged periods possibly without an apparent cause
- By size, where lymphadenopathy in adults is often defined as a short axis of one or more lymph nodes is greater than 10mm.[2][3]
