The Vang et al. [15] analysis of clear cell carcinoma in the female reproductive system (n=17) found that the immunohistochemistry was positive for CK7, CAM5.2, 34 beta E12, CEA, Leu-M1, vimentin, bcl-2, p53, and CA 125.ER, and HER-2/neu were expressed to different degrees but negativity for CK20 and PR. Here, ERBB2 is linked to clear cell adenocarcinoma.
