 Immunohistochemistry of HBME‐1, GAL‐3, CK19 in well‐differentiated tumor of uncertain behavior (WDT‐UB), follicular thyroid adenoma (FTA), and follicular variant papillary thyroid carcinoma (FV‐PTC). (A) In WDT‐UB, the reaction of the three markers increased, but was mainly in the cell membrane, and the staining was less intense. (B) In FTA, only occasional reaction with the three markers was found. (C) In infiltrative FV‐PTC, all of the three markers showed intense and diffuse reaction with the carcinoma cells. Original magnification: (A,C) ×200; (B) ×100.
