Usually this is localized (for example, an infected spot on the scalp will cause lymph nodes in the neck on that same side to swell). 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.
Lymphadenopathy or adenopathy is a disease of the lymph nodes, in which they are abnormal in size or consistency.Lymphadenopathy of an inflammatory type (the most common type) is lymphadenitis, [1] producing swollen or enlarged lymph nodes.
One or two supratrochlear lymph nodes are placed above the medial epicondyle of the humerus, medial to the basilic vein.. Their afferents drain the middle, ring, and little fingers, the medial portion of the hand, and the superficial area over the ulnar side of the forearm; these vessels are, however, in free communication with the other lymphatic vessels of the forearm.
Generalized lymphadenopathy is swollen lymph glands in many areas of the body. [1]Usually this is in response to a body-wide infectious disease such as influenza and will go away once the person has recovered, but sometimes it can persist long-term, even when there is no obvious cause of disease.
Paracortical hyperplasia is the preferential stimulation of the T cell compartment. It is caused by an abnormal expansion of the interfollicular zones but is confined within the lymph node capsule. The population of the compartment is cytologically polymorphous. Paracortical hyperplasia may be accompanied by vascular proliferation.
Experts explain whether or not allergies could be causing swollen lymph nodes in your neck or under your jaw, and when to see a doctor about enlarged glands.
Intrathoracic nodes are enlarged in 75 to 90% of all people; usually this involves the hilar nodes, but the paratracheal nodes are commonly involved. Peripheral lymphadenopathy is very common, particularly involving the cervical (the most common head and neck manifestation of the disease), axillary, epitrochlear, and inguinal nodes. [71]
Idiopathic multicentric Castleman disease (iMCD) is a subtype of Castleman disease (also known as giant lymph node hyperplasia, lymphoid hamartoma, or angiofollicular lymph node hyperplasia), a group of lymphoproliferative disorders characterized by lymph node enlargement, characteristic features on microscopic analysis of enlarged lymph node tissue, and a range of symptoms and clinical findings.
