TIGIT immunohistochemical results of composite type ATCs. In H&E-stained sections, ATC components showing pleomorphic/giant cell shape (left) were concomitantly seen with adjacent FTC components (right) (A). The FTC cells were completely negative for TIGIT, while ATC cells were starkly positive (B). In PTC-composite ATC, the PTC cells showed tall cell morphology with partial hobnail structures (H&E) (C). These neoplastic cells completely lacked immunoreactivity for TIGIT (D)
