H& E- and immunostaining of p53 and E-cadherin proteins in different tumor sections. A) H&E staining of the right-sided breast carcinoma showing an invasive carcinoma, grade 2, with focal lobular features. B) H& E staining of the right-sided breast carcinoma showing the lobular component. C, D) Immunostaining for E-cadherin. Positive cells (brownish) are present at the membrane but in a clearly lower portion within the component with lobular features. E, F) Immunostaining for p53 was negative for both, the invasive and the intraductal carcinoma.
