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
It most commonly affects individuals over the age of 65, due to the accumulation of genetic mutations that occur over time. [3] [18] CLL is rarely seen in individuals less than 40 years old. [19] Men are more commonly affected than women, although the average lifetime risk for both genders are similar (around 0.5-1%) .
It occurs primarily in elderly adults, far less frequency in younger adults, and rarely in children. Elderly adults present with B symptoms (i.e. fever, night sweats, and weight loss), swollen lymph nodes, and symptoms due to malignant cell infiltrations into the upper gastrointestinal tract, lungs, upper airways, and/or other organs.

Over 75% of all lymphadenopathies are observed as local, usually involving specifically the head and neck regions. [4] It has been estimated that patients who present lymphadenopathy has an estimated 1.1% chance of developing malignancy. [11] The rate of childhood malignancy associated with lymphadenopathy is low, however this increases with age.

Children often have generalized lymphadenopathy of the head and neck, or even PGL, without the finding of a sinister cause. At puberty this usually disappears. The immune system of some people may be sensitized by exposure to a living exogenous irritant such as a bacterial or viral infection , which then results in PGL after the organism has ...
