Figure 2. Representative blue SSLCs observed after single subareolar injection of methylene blue dye intraoperatively, showing that pathways of lymph flow arise from the areolar region, pass within the subcutaneous fatty tissue, and terminate at the SLNs in the axilla.

A: One blue SSLC from the areolar region to a single blue SLN. B: Two separate SSLCs from the areolar region, through diverging pathways, to two separate but adjacent SLNs. (1. injection site; 2. blue SSLC; 3.SLN).
