Figure 3 The histological examination and immunohistochemical profiling of the surgically resected tissue.
A: Results of hematoxylin and eosin staining; B: The expression of marker proteins specific for small cell neuroendocrine carcinoma; C: Immunohistochemical results for P40 and cytokeratin 5/6 protein expression; D and E: The expression of mismatch repair protein-related indicators postmeiotic segregation increased 2, mutS homolog 6, mutL homolog 1, mutS homolog 2, as well as the expression of tumor protein P53 and Ki67. SSTR2: Somatostatin receptor type 2; SYN: Synaptophysin; TTF-1: Thyroid transcription factor-1; CgA: Chromogranin A; CD56: Cluster of differentiation 56. MLH1: MutL homolog 1; MSH6: MutS homolog 6; MSH2: MutS homolog 2; PMS2: Postmeiotic segregation increased 2.
