What are the groups of axillary lymph nodes?
There are five axillary lymph node groups, namely the lateral (humeral), anterior (pectoral), posterior (subscapular), central and apical nodes. The apical nodes are the final common pathway for all of the axillary lymph nodes.
How many groups of axillary lymph nodes are there?
five groups
[2] The axillary lymph nodes arrange into five groups based on their anatomical relations. Collectively, they drain the wall of the thorax, breast, arm, and upper abdominal wall above the umbilicus.
What are the groups of lymph nodes?
There are three superficial regions on each side of the body where lymph nodes tend to cluster. These areas are the inguinal nodes in the groin, the axillary nodes in the armpit, and the cervical nodes in the neck.
What are the four groups of axillary nodes in the breast tissue?
Central axillary nodes Lying deep to the pectoralis minor muscle within adipose tissue of the axilla, they contain about 4-5 nodes and receive drainage from the breast, the brachial group, the pectoral group, and the subscapular group.
What are the 5 axillary lymph nodes?
What is bilateral axillary lymph nodes?
Axillary lymphadenopathy is characterized by swelling and inflammation of one or more of the 20 to 40 axillary lymph nodes in each armpit. The swelling may involve one armpit, which is known as unilateral, or both armpits, known as bilateral.
What is the normal size of an axillary lymph node?
Axillary lymph nodes, usually up to 1 cm but occasionally 1.5 cm in diameter, can be seen in normal subjects.
How many lymph nodes are in a group?
There are 20-40 nodes arranged in five principal groups: pectoral, subscapular, humeral, central, and apical.
What is considered a deep axillary lymph node?
Clinicians divide axillary lymph nodes into three levels. Level II and III lymph nodes are always deep and reported with 38525. Level I nodes may be either deep (reported with 38525) or superficial (38500), depending on the individual patient.
What level are axillary lymph nodes?
There are five groups of lymph nodes in the axilla: three in level I, which is inferolateral to the pectoralis minor; one group in level II behind the pectoralis minor; and one group superomedial to the pectoralis minor in level III.
