Immunohistochemistry of seminal vesicle tumor (Envision, × 10, by OLYMPUS BX53). a H&E staining showed that the tumor cells were denser than interstitial cells. IHC findings showed that most tumor cells were strongly positive for calponin (b) and moderately positive for SMA (c) and desmin (d). None of the tumor cells showed Vimentin expression, while nonneoplastic endothelial cells expressed Vimentin (e). The positive rate of Ki-67 (f) was low
