VIM and clear cell renal carcinoma: Specifically, vimentin (8/12 cases), 34βE12 (1/12 cases), CA125 (0/12 cases), ER (1/12 cases), and PgR (1/12 cases) are positive in renal cell carcinoma, whereas vimentin (1/10 cases), 34βE12 (10/10 cases), CA125 (8/10 cases), ER (7/10 cases), and PgR (6/10 cases) tend to be positive in ovarian clear cell carcinoma.24 In our cases, the histopathological features characteristic of clear cell renal cell carcinoma were observed, making the diagnosis possible.
