Ultrasound of the sentinel node in melanoma patients: echo-free island is a discriminatory morphologic feature for node positivity

Unlike breast and thyroid cancer, the use of ultrasound (US)-guided fine needle aspiration cytology (FNAC) for preoperative staging is limited in melanoma. New US morphology criteria have shown that US-FNAC can correctly identify 50% of all involved sentinel nodes (SN) in melanoma patients before su...

Zusammenfassung:	Unlike breast and thyroid cancer, the use of ultrasound (US)-guided fine needle aspiration cytology (FNAC) for preoperative staging is limited in melanoma. New US morphology criteria have shown that US-FNAC can correctly identify 50% of all involved sentinel nodes (SN) in melanoma patients before surgical excision. The aim of this study was to examine a new criterion: the echo-free island (EFI). A total of 1000 consecutively staged melanoma patients (Breslow thickness>1 or
