Truncal Melanoma

  • Truncal melanomas:
    • Have a higher rate of mapping on lymphoscintigraphy:
      • To multiple lymph node basins
  • McHugh et al. (2006):
    • Found 23% of patients with primary truncal melanomas:
      • To have multiple lymphatic basin drainage
  • Other series have described a rate of multiple lymphatic basin drainage for truncal melanomas:
    • Between 29% to 46%
  • The standard of care and rationale for preoperative lymphoscintigraphy:
    • It assists with identifying patients with multiple lymphatic basins:
      • When identified, a sentinel node biopsy should be performed in each basin
