Gastric Endocrine Cell Carcinoma Coexistent with Adenocarcinoma
Figure 2
Proliferation of small and heterogeneous cancer cells with rich chromatin and fibrous septum with rich vessels at connective tissues was evident (hematoxylin and eosin) (a). Atypical cells forming glandular structures were evident (hematoxylin and eosin) (b). Immunostaining of small and heterogeneous cancer cells by chromogranin (c), synaptophysin (d), cytokeratin 7 (e), and EMA (f) was positive.
