Contralateral axillary sentinel lymph node drainage in breast cancer: a case report.
BACKGROUND
Since the introduction of sentinel node (SN) mapping in breast cancer, extra-axillary lymph node sites of breast tumor drainage are discovered in about one-quarter of cases, especially after intraparenchymal injection. In most such cases, an ipsilateral axillary SN is associated with an extra-axillary SN. Non visualization of ipsilateral axillary SN and extra-axillary SN drainage are often associated with an increased risk of axillary involvement.


METHODS
We report a case of contralateral axillary SN drainage on lymphoscintigraphy in a breast cancer patient with a history of bilateral reduction mammoplasty and no ipsilateral axillary lymph node involvement.
