Immunohistochemistry of steroid hormone receptors in hormone-dependent cancers. (A) Expression of ERα in endometrial carcinoma tissue; (B) Expression of androgen receptor (AR) in endometrial carcinoma tissue. AR was detected in both carcinoma cells and stromal cells (arrow heads) in this case; (C) Expression of ERβ in non-pathological epithelia of prostate tissue; (D) Expression of ERβ5 in breast carcinoma tissue. Top photographs are of a lower magnification (scale bar, 200 μm), and bottom photographs are of a higher magnification (scale bar, 100 μm).
