An aberrant lymph node containing metastatic melanoma detected by sentinel node biopsy.

The use of sentinel node biopsy in the staging of malignant melanoma has led to the identification of lymph nodes outside the described regional basins, so-called aberrant nodes. We present a case in which such an aberrant sentinel node was found to be positive for metastatic disease, and discuss our surgical management.
