Sentinel node (SN) localization using lymphoscintigraphy can be complicated by skin contamination from radiopharmaceuticals. Careful procedural observation prevented misinterpretation of the SN location in this melanoma case.

Area of Science:

  • Nuclear medicine imaging
  • Dermatologic oncology
  • Surgical oncology

Background:

  • Sentinel node biopsy is crucial for melanoma staging.
  • Lymphoscintigraphy is a standard technique for sentinel node localization.
  • Potential complications include radiopharmaceutical skin contamination.

Observation:

  • A 60-year-old male patient with back melanoma underwent lymphoscintigraphy.
  • Accidental skin contamination with the radiopharmaceutical occurred during dose administration.
  • Contamination posed a risk of misidentifying the sentinel node location.

Findings:

  • Despite skin contamination, careful monitoring of the lymphoscintigraphy procedure was performed.
  • The potential misinterpretation of the sentinel node's true location was successfully avoided.

  • Accurate sentinel node identification was maintained throughout the procedure.

    • Implications:

    • Highlights the importance of meticulous technique in lymphoscintigraphy.
    • Emphasizes vigilance to mitigate risks associated with radiopharmaceutical handling.
    • Ensures accurate staging and appropriate treatment planning for melanoma patients.
