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 ...
Infectious lymphadenitis affecting lymph nodes in the neck is often called scrofula. Lymphadenopathy is a common and nonspecific sign . 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 .
Persistent generalized lymphadenopathy (PGL) is enlarged, painless, non-tender lymph nodes occurring in a couple of different areas for more than three to six months for which no other reason can be found. [1] To expand, the common site where PGL occurs is within the head and neck region; parotid gland alterations and nasopharyngeal lymphatic ...
The most common causes of enlargement of the submandibular lymph nodes are infections of the head, neck, ears, eyes, nasal sinuses, pharynx, and scalp. [1] The lymph glands may be affected by metastatic spread of cancers of the oral cavity, anterior portion of the nasal cavity, soft tissues of the mid-face, and submandibular salivary gland. [1]
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 ...
Superficial lymph glands and lymphatic vessels of head and neck. (Superficial cervical labeled at center left.) The superficial cervical lymph nodes are lymph nodes that lie near the surface of the neck. Some sources state simply that they lie along the external jugular vein, [1] while other sources state that they are only adjacent to the ...
Subscapular axillary lymph nodes. A posterior or subscapular group of six or seven glands is placed along the lower margin of the posterior wall of the axilla in the course of the subscapular artery. The afferents of this group drain the skin and muscles of the lower part of the back of the neck and of the posterior thoracic wall; their ...
Follicular hyperplasia (FH) is a type of lymphoid hyperplasia and is classified as a lymphadenopathy, which means a disease of the lymph nodes. It is caused by a stimulation of the B cell compartment and by abnormal cell growth of secondary follicles. This typically occurs in the cortex without disrupting the lymph node capsule. [1]
