Figure 1: Immunocytochemistry of CEA, TTF-1, p63, and SYN. (a) The immunostain of CEA in adenocarcinoma. It showed membrane positive (IHC: CEA x400). (b) The immunostain of TTF-1 in adenocarcinoma. It showed nuclei positive (IHC: TTF-1 x400). (c) A case of squamous cell carcinoma, expressed with p63. The nuclei was stained positive (p63 x400). (d) The immunostain of SYN in small cell carcinoma (IHC : SYN x400)
