Groups of immunohistochemical staining results. (A) Negativity for CD10 throughout the tumor suggested that this was not a solitary fibrous tumor or an endometrial stromal sarcoma but rather PBML, ×400; (B) negativity for SP-B throughout the tumor suggested lung metastases, ×400; (C) weak positivity for Ki-67 (<5%) suggested that the low proliferation index of tumor cells, ×400; (D) negativity for CK throughout the tumor suggested that the tumor was not of epithelial origin, ×400; (E) strong positivity for desmin throughout the tumor suggested that the tumor was derived from smooth muscle, ×400; (F) strong positivity for desmin-2 throughout the tumor suggested that the tumor was derived from smooth muscle, ×400; (G) strong positivity for the progesterone receptor (PR) throughout the tumor suggested that the tumor cells originated in the uterus and were regulated by the PR, ×400; (H) strong positivity for the estrogen receptor (ER) throughout the tumor suggested that the tumor cells originated in the uterus and were regulated by the ER, ×400; (I) strong positivity for SMA showed that the tumor was derived from smooth muscle, ×400.
