*comment: margins are not inviolate and may be modified by proximity to critical structures with attention to lymphatic drainage patterns
**comment: Mohs surgery may be considered for melanoma with lentigo maligna extending beyond the 1 cm margin encompassing melanoma
#comment: consider nodal basin US prior to SLNB for melanoma patients with equivocal regional LN physical exam. Nodal basin US is NOT a substitute for SLNB.
_______
Follow-up
- Modify significantly according to prognosis
- Avoidance of sun exposure
- Surveillance for Stage IA to IIA as per NCCN Guidelines (ref Swetter et al. 2021)
- All melanoma patients: Skin examination and surveillance at least once a year for life is recommended
- H&P every 6-12 months x 5 years, then as clinically indicated
- Routine blood tests NOT recommended
- Routine imaging to screen for asymptomatic metastatic disease NOT recommended
- All patients with melanoma treated for cure should have at least yearly follow-up with dermatology to permit total-body surveillance
