In the evolution of melanoma care, it has repeatedly been demonstrated that less can be more. Once, at first sight of a primary tumor, entire limbs were sacrificed to prevent metastasis. Not long ago, 3-5-cm margins around the primary were standard in surgical excision, whereas now 1-cm margins are routine. And just a generation ago, primaries deemed high-risk most often led to complete elective regional lymph node dissection (ELND). This practice ended with the gradual acceptance of sentinel lymph node biopsy (SLNB), the now standard tissue-sparing surgical technique developed by Dr. Donald Morton in the early 1990s. However, the role of SLNB in clinical practice continues to be debated.
