Surgical Margins for Wide Excision of Primary Melanoma
- The National Comprehensive Cancer Network (NCCN) recommends wide excision of margins of primary melanoma.
- The choice of clinical margins is based on the tumor thickness.[1]
- The margins may be individualized to accomodate anatomic and functional considerations.[1]
| Tumor thickness | Recommended Clinical Margins |
| In situ | 0.5 cm |
| ≤ 1 mm | 1 cm |
| > 1 mm – 2 mm | 1-2 cm |
| > 2 mm – 4 mm | 2 cm |
| > 4 mm | 2 cm |

Complete Lymph Node Dissection
The 2013 National Comprehensive Cancer Network (NCCN) recommends complete dissection of involved nodal basin is recommended.[1]
- Specific considerations for the groin lymph nodes
- Indications for iliac and obturator lymph node dissection:
- Positive pelvic CT, or
- Cloquet’s node is positive
- Elective iliac and obturator lymph node dissection
- Clinically positive superficial node, or
