Fig 4. Androgen, estrogen, and progesterone receptors in carcinosarcoma.

Fig 4

Hematoxylin and eosin (H&E) stain of a case of uterine carcinosarcoma showing a biphasic pattern composed of high-grade carcinomatous and sarcomatous components (case #60, S1 Table). The corresponding androgen receptor (AR), estrogen receptor (ER), and progesterone receptor (PR) immunostains show positive nuclear staining for AR in both carcinomatous and sarcomatous components. ER and PR are negative in the two components of the cancer (20× objective).
