However, inguinal lymph nodes of up to 15 mm and cervical lymph nodes of up to 20 mm are generally normal in children up to age 8–12. [ 38 ] Lymphadenopathy of more than 1.5–2 cm increases the risk of cancer or granulomatous disease as the cause rather than only inflammation or infection .
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]
The primary function of lymph nodes is the filtering of lymph to identify and fight infection. In order to do this, lymph nodes contain lymphocytes, a type of white blood cell, which includes B cells and T cells. These circulate through the bloodstream and enter and reside in lymph nodes. [26] B cells produce antibodies.
In immunologically normal individuals, histologic findings include the presence of small B cells located in the extrafollicular or, rarely, the follicular area of normal or minimally hyperplastic lymph nodes. These cells are commonly EBV+, express EBER viral genes, and carry the virus in its latency I or II phase.

Although lymphocytes are usually considered mature, as seen in blood tests, they are certainly not ...
