Answer

Differentiation of the sentinel node from second-tier nodes can be made by the following:

  • The presence of a lymphatic channel leading to the sentinel node

  • The sequence of appearance (the sentinel node appears first)

  • The intensity of uptake (the sentinel node has more activity)

Confirmation needs blue-dye corroboration.
