Claudin-4 can be used as a single marker for carcinoma with high sensitivity and superior specificity compared with MOC-31 and Ber-EP4. Mesothelial lineage can be ruled out when claudin-4 is positive. In equivocal cytology samples with few scattered cells of interest, a panel of claudin-4 and Ber-EP4 results in the highest combined sensitivity and specificity.
