Cytoplasmic FOXC1 immunoreactivity in serous ovarian tumors and normal endometrium tissue (magnification, ×400). (A) The majority of neoplastic cells are positive. Positive immunostaining of FOXC1 was observed exclusively in the cytoplasm of glandular epithelium cells in serous cystadenoma; no nuclear positivity was observed; (B) Positive immunostaining of FOXC1 was observed exclusively in the cytoplasm of glandular epithelium cells in serous borderline cystadenoma; (C) Positive immunostaining of FOXC1 was observed exclusively in the cytoplasm of glandular epithelium cells in well-differentiated serous cystadenocarcinoma. (D) FOXC1 immunostaining in normal endometrium tissue was used as a positive control. Positivity was observed exclusively in the cytoplasm of endometrial glandular cells.
