Figure 2

Lymphoscintigraphic study performed in a patient affected by invasive MC breast cancer (two nodules located in the upper outer and inner quadrants of the left breast). The patient underwent two subsequent lymphoscintigraphies after each intradermal injection of the tracer over the two neoplastic foci (2ID Group), showing two sentinel lymphatic channels mainly affering to different SLNs. A) First lymphoscintigraphy performed after the first radioisotope injection over the tumoral focus located in the upper outer quadrant of the breast. One SLN is visualized in the axilla. An other LN shows low radioactivity. B) Second lymphoscintigraphy performed in the same patient after the second radioisotope injection over the other tumoral focus located in the upper inner quadrant of the breast. One different pathway is visualized traversing the outer upper quadrant of the breast, which is mainly connected to the second SLN visualized after the first injection.
