  1. *One false negative
  2. †Two negative cases showed indeterminate results with IC
  3. ¶Two SLN were positive unequivocally with IC but negative by SP
  4. 1Only D&E were submitted as sentinel LN (A,B,C were submitted as non-SLN);
  5. 2Atypical Spitzoid nevus, recommended SLN biopsy;
  6. 3Dysplastic nevus, recommended SLN biopsy;
  7. 4Final results summarizing findings in all SLN in a particular case after immunostaining of permanent sections: total number of positive cases- 8 and negative cases- 33.
  8. Abbreviations in alphabetical order: +, positive for melanoma metastases; -, negative for melanoma metastases; cn, capsular nevus; FR, final result; IC, rapid intraoperative immunocytochemistry; Intm, indeterminate for melanoma metastases; LN, sentinel and non-sentinel lymph nodes; N, negative; P, positive; SP, final result on permanent sections.
