Description

The interpectoral nodes are a collateral axillary node group, made up of one to four nodes. They are located superficial to the pectoralis minor muscle, in close association with the branches of the pectoral branches from the thoracoacrominal artery. They receive afferent lymph vessels from the mammary glands and their efferent vessels drain into the infraclavicular nodes (Földi et al., 2012).
