Paracortical hyperplasia/ Interfollicular hyperplasia: It is seen in viral infections, skin diseases, and nonspecific reactions.

Follicular hyperplasia: This is the most common type of reactive lymphadenopathy.

There are seven distinct patterns of benign lymphadenopathy: Most cases of reactive follicular hyperplasia are easy to diagnose, but some cases may be confused with follicular lymphoma. It may be separated into major morphologic patterns, each with its own differential diagnosis with certain types of lymphoma.

'Lymphadenopathy syndrome' has been used to describe the first symptomatic stage of HIV progression, preceding a diagnosis of AIDS. Generalized lymphadenopathy is an early sign of infection with human immunodeficiency virus (HIV), the virus that causes acquired immunodeficiency syndrome (AIDS).

Autoimmune: systemic lupus erythematosus and rheumatoid arthritis may have a generalized lymphadenopathy.

Secondary: metastasis, Virchow's node, neuroblastoma, and chronic lymphocytic leukemia.

Primary: Hodgkin lymphoma and non-Hodgkin lymphoma give lymphadenopathy in all or a few lymph nodes.

Infectious causes of lymphadenopathy may include bacterial infections such as cat scratch disease, tularemia, brucellosis, or prevotella, as well as fungal infections such as paracoccidioidomycosis.

Mesenteric lymphadenitis after viral systemic infection (particularly in the GALT in the appendix) can commonly present like appendicitis.

Plasma cell variant of Castleman's disease - associated with HHV-8 infection and HIV infection.

Toxoplasmosis, a parasitic disease, gives a generalized lymphadenopathy ( Piringer-Kuchinka lymphadenopathy).

It is also a sign of cutaneous anthrax and human African trypanosomiasis.

Infectious mononucleosis is an acute viral infection usually caused by Epstein-Barr virus and may be characterized by a marked enlargement of the cervical lymph nodes.

The most distinctive sign of bubonic plague is extreme swelling of one or more lymph nodes that bulge out of the skin as 'buboes.' The buboes often become necrotic and may even rupture.

Reactive: acute infection (e.g., bacterial, or viral), or chronic infections ( tuberculous lymphadenitis, cat-scratch disease ).

Lymph node enlargement is recognized as a common sign of infectious, autoimmune, or malignant disease. Lymphadenopathy is frequently idiopathic and self-limiting.Ĭauses Retroperitoneal lymphadenopathies of testicular seminoma embrace the aorta. Common causes include infections (from minor causes such as the common cold and post-vaccination swelling to serious ones such as HIV/AIDS), autoimmune diseases, and cancer. Lymphadenopathy is a common and nonspecific sign. Infectious lymphadenitis affecting lymph nodes in the neck is often called scrofula. Inflammation of the lymphatic vessels is known as lymphangitis. In clinical practice, the distinction between lymphadenopathy and lymphadenitis is rarely made and the words are usually treated as synonymous.

Lymphadenopathy of an inflammatory type (the most common type) is lymphadenitis, producing swollen or enlarged lymph nodes. Lymphadenopathy or adenopathy is a disease of the lymph nodes, in which they are abnormal in size or consistency.
