The presence of swollen inguinal lymph nodes is an important clinical sign because lymphadenopathy (swelling) may indicate an infection, or spread as a metastasis from cancers, such as anal cancer and vulvar cancer. Inguinal lymph nodes may normally be up to 2 cm. [1] The cut-off value for normal sized inguinal nodes is up to 10 mm. [6]
Lymphadenopathy may be classified by: Size, where lymphadenopathy in adults is often defined as a short axis of one or more lymph nodes is greater than 10mm. [29] By extent: 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
Nodes are typically around 15 mm in length in adults, and decrease in size during old age. [1] They tend to be some of the largest lymph nodes in the cervical chain due to their significant lymphatic drainage. [1]
Follicular hyperplasia is common in children and young adults, but is not limited to any age; it is also common among the elderly and is non-sex specific. [1] Children often experience reactive lymph nodes when they are younger due to new exposure of environmental pathogens , even without development of an infection.
However, when two or more lymph node groups are involved, it is called generalized lymphadenopathy. Usually this is in response to significant systemic disease and will subside once the person has recovered. Sometimes it can persist long-term, even when no explanation for the lymphadenopathy can be found.
The signs and symptoms of Kikuchi disease are fever, enlargement of the lymph nodes (lymphadenopathy), skin rashes, and headache. [7] In sixty to ninety percent of cases, lymphadenopathy presents in the posterior cervical lymph nodes with diameter enlargement typically being between one and two centimeters, but up to seven centimeters has been reported in literature.
The axillary lymph nodes are arranged in six groups: [2] Anterior (pectoral) group: Lying along the lower border of the pectoralis minor behind the pectoralis major, these nodes receive lymph vessels from the lateral quadrants of the breast and superficial vessels from the anterolateral abdominal wall above the level of the umbilicus.
CT scan of the chest showing bilateral lymphadenopathy in the mediastinum due to sarcoidosis. Bilateral hilar lymphadenopathy is a bilateral enlargement of the lymph nodes of pulmonary hila. It is a radiographic term for the enlargement of mediastinal lymph nodes and is most commonly identified by a chest x-ray.
