Sentinel lymph node biopsy in melanoma: Which hot nodes should be harvested and is blue dye really necessary?

Our data do not support the continued use of blue dye in SLNB for melanoma, as it does not improve the sensitivity of the test. This series adds to growing evidence, suggesting that the '10% rule' with the inclusion of blue nodes should be reconsidered and that radiocolloid tracer alone is sufficient for sentinel node localisation.
