Figure Lengend Snippet: Alcohol‐fixed cytological smears of EGLs and HNF4α immunocytochemical staining. (A,B) Case of cytologically diagnosed adenocarcinoma, histologically confirmed as HPVA ECA, showing a large cluster with nuclei with intense and diffuse HNF4α expression (arrowhead) and normal squamous cells without HNF4α staining (arrow). (C,D) Case of cytologically diagnosed AGC, histologically confirmed as NHPVA ECA, showing slightly nuclear atypia with HNF4α staining (arrowhead) and normal glands without HNF4α staining (arrow). (E,F) Case of cytologically diagnosed AGC, histologically confirmed as LEGH, showing yellowish mucin with HNF4α staining (arrowhead) and normal glands without HNF4α staining (arrow). (A,C,E) Papanicolaou staining, 200× magnification. (B,D,F) HNF4α immunocytochemical staining, 200× magnification. ECA indicates endocervical adenocarcinoma; EGL, endocervical glandular lesions; HNF, hepatocyte nuclear factor; HNF4α, hepatocyte nuclear factor 4 alpha; HPVA, human papillomavirus–associated; LEGH, lobular endocervical glandular hyperplasia; NHPVA, nonhuman papillomavirus–associated.
Article Snippet: Then, the slides were incubated with anti‐human HNF4α mouse monoclonal antibody (#H1415, recognizing the C‐terminal isoform, 1:1000; Perseus Proteomics, Tokyo, Japan) at 4°C overnight.
