PAX8 expression is strong and diffuse in clear cell adenocarcinoma of lower urinary tract (CCACLUT; 4 A-4B; 200X), nephrogenic adenoma (4E-4 F; 200X), and clear cell adenocarcinoma of the female genital tract (CCACFGT; ovarian primary; 4I-4 J; 200X). Somewhat patchy but persistent Napsin A was present in CCACLUT (4 C; 200X), NA (4G; 200X), and CCACFGT (4 K; 200X). p63 was all negative in CCACLUT (4D; base of the urothelium as control; 200X) and NA (4 H; 200X); as well as all but one CCACFGT cases (4 L; 200X).
