Immunohistochemical features of blastomatoid carcinosarcoma (BCS). a β-catenin was nucleus positive in squamoid morule cells of L-FLAC and membrane positive in columnar epithelial of H-FLAC and dot-positive in mesenchymal cells b (× 400). c Neuroendocrine marker CD56 were expressed in both epithelial and mesenchymal cells. Some epithelial cells were positive for CDX2 d and the mesenchymal cells was positive for S-100 e in the third patient (× 400). f The proliferation index of epithelial components was significantly higher than that of mesenchymal (× 400)
