GATA3 and metastatic malignant neoplasm in the lymph nodes: In this study, using immunohistochemical staining we investigated the expression of GATA3 in a large series of 72 primary EMPDs (45 with intraepithelial disease only, 26 with both intraepithelial disease and invasive adenocarcinoma including 14 also with lymph node metastasis, 1 with metastatic adenocarcinoma only for study) in male and female genital regions to explore the potential diagnostic utility of GATA3 in these tumors.
