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.
In women, it is most prevalent in an upper limb after breast cancer surgery, especially axillary lymph node dissection, [15] and occurs on the same side of the body as the surgery. Breast and trunk lymphedema can also occur but go unrecognised as there is swelling in the area after surgery, and its symptoms ( peau d'orange and an inverted ...
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 ...
Anatomical terminology. [edit on Wikidata] The tail of Spence (Spence's tail, axillary process, axillary tail) has historically been described as an extension of the tissue of the upper outer quadrant of the breast traveling into the axilla. [1] The "axillary tail" has been reported to pass into the axilla through an opening in the deep fascia ...
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 ...
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 ...
Lymphadenopathy of the axillary lymph nodes can be defined as solid nodes measuring more than 15 mm without fatty hilum. [36] Axillary lymph nodes may be normal up to 30 mm if consisting largely of fat. [36] In children, a short axis of 8 mm can be used. [37]
Radical mastectomy is a surgical procedure that treats breast cancer by removing the breast and its underlying chest muscle (including pectoralis major and pectoralis minor), and lymph nodes of the axilla (armpit). Breast cancer is the most common cancer among women. During the early twentieth century it was primarily treated by surgery, when ...
