In this case, the clear tumor cells showed positivity of MUC-1 (Figure 3G), cytokeratin 7 (Figure 3D), and cytokeratin 19 (Figure 3E), and showed negativity of vimentin (Figure 3F) and neuroendocrine markers, which indicate pancreatic clear cell carcinoma with ductal phenotype. This evidence concerns the gene KRT19 and neoplasm.
