Lymph nodes may become enlarged in malignant disease. This cervical lymphadenopathy may be reactive or metastatic. [1] Alternatively, enlarged lymph nodes may represent a primary malignancy of the lymphatic system itself, such as lymphoma (both Hodgkin's and non-Hodgkin's), [6] lymphocytic leukemia, [1] Lymphadenopathy that lasts less than two weeks or more than one year with no progressive ...
The classification of the cervical lymph nodes is generally attributed to Henri Rouvière in his 1932 publication "Anatomie des Lymphatiques de l'Homme" [6] [7] Rouviere described the cervical lymph nodes as a collar which surrounded the upper aerodigestive tract, consisting of submental, facial, submandibular, parotid, mastoid, occipital and retropharyngeal nodes, together with two chains ...
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. Still, an increasing size and persistence over time ...

Lymph nodes of the lungs: The lymph is drained from the lung tissue through subsegmental, segmental, lobar and interlobar lymph nodes to the hilar lymph nodes, which are located around the hilum (the pedicle, which attaches the lung to the mediastinal structures, containing the pulmonary artery, the pulmonary veins, the main bronchus for each side, some vegetative nerves and the lymphatics) of ...
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 ...
The deep cervical lymph nodes are subdivided into a superior group and an inferior group. [3] [4] Alternatively, they can be divided into deep anterior cervical lymph nodes and deep lateral cervical lymph nodes. [citation needed] They can also be divided into three groups: "superior deep jugular", "middle deep jugular", and "inferior deep ...
The anterior cervical lymph nodes are a group of nodes found on the anterior part of the neck, in front of the sternocleidomastoid muscle. These can be grouped into a deep and superficial group . The superficial group drain the superficial surfaces of the anterior neck.
