Mapping of the ARM lymph nodes in the axilla. Field A is the area between the axillary vein and the second intercostobrachial nerve and between the anterior edge of the latissimus dorsi muscle and the thoracodorsal neurovascular bundle. Field B is the area medially adjacent to field A and close to the anterior serratus muscle (the chest wall). Field C is the area surrounding the second intercostobrachial nerve, the anterior serratus muscle, and the thoracodorsal neurovascular bundle. Field D is the area below field A and laterally adjacent to field C. Field E is the area above the axillary vein.
