The drainage of the 38 THE BREAST deeper portions of the breast into the lymph channels of the peri-thoracic muscles andtheir fascial coverings is held by Gerota, Poirier, Cuneo and Delamere, and Sappey tobe subsidiary, under normal conditions, to the cutaneous route. The mammary lymphvessels are divided by Poirier and his co-workers into the cutaneous and the cutaneous lymph vessels differ in distribution in the central and peripheral portions.

In the former two main trunks arise from a central sub-areolar plexus, runabove and below the areola and turn transversely outward to reach the thoracic group ofaxillary nodes. Some small trunks arise in the upper peripheral portions and pass overthe clavicle to reach the supra-clavicular nodes of the deep cervical chain. Somemammary trunks seem to cross from one side of the chest to the other, thus creating ananastomosis between the two sets of mammary lymph vessels. SURGICAL ANATOMY OF THE BREAST 39 Olsner and Roeffel have demonstrated the existence of a lymphatic trunk that arisesin the lower inner quadrant of one breast and goes directly to the lymph nodes of theopposite axilla. The central cutaneous lymphatics begin in a fine network, beneath the areola, andnipple, and unite into several trunklets. These latter break up to
