E-cadherin and calretinin as immunocytochemical markers to differentiate malignant from benign serous effusions

Figure 1 Immunocytochemistry of E-cadherin in the cells from a malignant ascites specimen. Carcinoma cells were mainly stained at cell membranes. Inflammatory cells without stain-ing were as control (Original magnification, × 400).

Figure 2 Immunocytochemistry of calretinin in the cells from a malignant ascites specimen. Mesothelial cells were stained strongly and some of them like “fried eggs”. Carcinoma cells and inflammatory cells without staining were as control (Original magnification, × 400).
