CDH1 and neoplasm: The differentiated tumour tissue (hepatoid and reserve cells) displayed strong membranous expression of high-molecular-weight cytokeratin (34βE12) (Figure 3(A)), low cytoplasmic expression for pan-cytokeratin (AE1/AE3) (Figure 3(B)), strong membranous E-cadherin expression (Figure 3(C)) and was negative for vimentin staining (Figure 1(D)).
