Photomicrographs showing immunohistochemistry for estrogen and progesterone receptors. (A and B) Epithelioid cells in both primary and metastatic foci were negative for estrogen receptors (× 400). (C) Pancreatic islet cells showed a weakly positive reactivity for estrogen receptos (× 400). (D and E) Epithelioid cells in both primary and metastatic foci showed a strongly positive reactivity for progesterone receptors (× 400). (F) Pancreatic islet cells showed a strongly positive reactivity for progesterone receptors (× 400).
