To our experience the presence of black pigmentation in vive thyroid tissue cervical lymph nodes before ligating the arteries was associated with differentiated thyroid cancer (DTC). The goal of this study was to evaluate the association between black pigmentation and DTC. 615 patients who were underwent thyroidectomy were assessed during operation by a single surgeon during 5 years from 2013 to 2018 and the presence of black pigmentation was evaluated in gross pathology before cuttning the arteries of thyroid. Then the final pathology diagnosis was assessed with presence or absence of this black pigmentation. From 615 patients, 368 patients had black pigmentaion. The sensitivity and specificity was 98% and 96% respectivley the positive predictive value of this finding during operation was 97%. The presence of black pigmentation was significantly greater in DTC group (P=0.017). This study showed that black pigmentation can be a good sign as a gross surgical pathology of DTC and whenever it is observed, it can be a good guide for doing the total thyroidectomy by means of cancer surgery.
