The insets show that this tumor is positive for TTF-1 and negative for synaptophysin and chromogranin. B) Another slice from the same biopsy specimen shows small-cell lung cancer (hematoxylin and eosin staining, marked with arrow). The insets show that this tumor is positive for TTF-1, synaptophysin, and chromogranin. chr, chromogranin; syn, synaptophysin; TTF, TTF-1.
