Lymph Vessels of the Skin of the Dorsal, Lateral, and Ventral Thoracic Wall

The lymph vessels of the dorsal, lateral and ventral thoracic wall, in the region caudal to the muscles of the shoulder and brachium (Figure 13), drain to the axillary lymph node (Figure 13: 13) and to a lesser extent to the superficial cervical lymph nodes (Figure 13: 3, 3’). Lymph drainage to the superficial cervical lymph nodes occurs from the area of the skin adjacent to the caudal angle of the scapula, as shown in Figure 13. If an accessory axillary lymph node (Figure 13: 4) is present, some of the lymph vessels mentioned above first drain into it before draining into the axillary lymph node.
