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.
Axillary lymph nodes. The axillary lymph nodes or armpit lymph nodes are lymph nodes in the human armpit. Between 20 and 49 in number, they drain lymph vessels from the lateral quadrants of the breast, the superficial lymph vessels from thin walls of the chest and the abdomen above the level of the navel, and the vessels from the upper limb.
Supraclavicular lymph nodes. Supraclavicular lymph nodes are lymph nodes found above the clavicle, that can be felt in the supraclavicular fossa. The supraclavicular lymph nodes on the left side are called Virchow's nodes. [1] It leads to an appreciable mass that can be recognized clinically, called Troisier sign. [2]
Axillary lymphadenopathy. Axillary lymphadenopathy is distinguished by an increase in volume or changes in the morphology of the axillary lymph nodes. It can be detected through palpation during a physical examination or through changes in imaging tests. On a mammogram (MMG), normal lymph nodes typically appear oval or reniform with a ...
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. 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 ...
The axillary or inguinal lymph nodes may be enlarged due to the swelling. Enlargement of the nodes lasting more than three weeks may indicate infection or other illnesses (such as sequela from breast cancer surgery) requiring further medical attention. [34] Diagnosis or early detection of lymphedema is difficult.
Tuberculous lymphadenitis. Peripheral tuberculous lymphadenitis (or tuberculous adenitis) is a form of tuberculosis infection occurring outside of the lungs. [1] In general, it describes tuberculosis infection of the lymph nodes, leading to lymphadenopathy. When cervical lymph nodes are affected, it is commonly referred to as " Scrofula." [2]
