Carbon dye histologically confirms the identity of sentinel lymph nodes in cutaneous melanoma

Abstract

Carbon dye used in LM/SL for melanoma permits the histologic confirmation of SNs. Carbon particles facilitate histologic evaluation by directing the pathologist to the SNs most likely to contain tumor. The location of carbon particles within SNs may assist the pathologist in the detection of metastases, thereby decreasing the histopathologic false-negative rate of LM/SL and subsequently reducing the same-basin recurrence rate.
