Photomicrographs of villous tissue showing haematoxylin and eosin staining and p57KIP2 immunostaining. a and b; (haematoxylin and eosin original magnification x40) demonstrate villous dysmorphism within the spectrum of that seen in molar pregnancies but not typical of complete or partial hydatidiform mole. c and d; (original magnification x100, immunostained with avidin-biotin detection system and haemtoxylin counterstain) show associated absence of villous p57KIP2 expression
