Figure 4
The immuno-phenotypes of high-grade carcinoma, comparing with those of typical AdCC. The high-grade carcinoma component showed strong and diffuse positivity for EMA (A: immunostaining x200), whereas the typical AdCC component showed limited positivity forthe true lumens in the cribriform growth area (B: immunostaining x200). The high-grade carcinoma component was negative for ASMA (C: immunostainng x200: the blood vessels were positive), whereas the peripheral cells adjacent the pseudocysts in the AdCC area were positive for ASMA (D: immunostaining x200). The high-grade carcinoma component was negative for p63 (E: immnostaining x200: the involved myoepithelial cells were positive), whereas the peripheral cells adjacent the pseudocysts in typical AdCC area were positive for p63 (F: immunostaining x200).
