The pathological descriptions of different subtypes of TNETs. A, E, I and M, the HE staining of typical carcinoid, atypical carcinoid, large cell neuroendocrine carcinoma and small cell carcinoma, respectively. B, F, J and N, immunocytochemistry staining indicated the positive expression of CgA in the four subtypes, respectively. C, G, K and O, immunocytochemistry staining indicated the positive expression of Syn in the four subtypes, respectively. D, immunocytochemistry staining indicated the 3% of ki-67 expression in typical carcinoid. H, immunocytochemistry staining indicated the 5% of ki-67 expression in atypical carcinoid. L Immunocytochemistry staining indicated the 5% of ki-67 expression in large cell neuroendocrine carcinoma. P Immunocytochemistry staining indicated the 70% of ki-67 expression in small cell carcinoma. All the pictures were shown in 150x. HE, hematoxylin–eosin; CgA, chromogranin A; Syn, synaptophysin
