These represent the most typical immunostaining patterns but aberrant staining may occur in individual neoplasms.
↵* Rectal adenocarcinomas may be CK7 positive.
↵† Non-HPV-related cervical adenocarcinomas may be p16 negative.
CEA, carcinoembryonic antigen; D, diffusely positive; ER, oestrogen receptor; F, focally positive; HPV, human papillomavirus; N, negative.
