3 Tumour Size   Length x Width x Thickness cm  
4 Tumour Configuration   Polypoid, Ulcerating, Infiltrative If polypoid, sessile or pedunculated (length of pedicle). For APR, apparent depth of inv.
5 Histologic Type     WHO classification
      Intraepithelial Neoplasia Squamous, Glandular, Pagets
        Note re Anal Pagets and CK7/20
      Squamous Cell Carcinoma Anal transition zone tumours usually are a mix of Lg Cell Non-keratinizing SCC and Basaloid SCC. The WHO no longer subclassifies SCC. "Cloacogenic" / "Transitional" terms are no longer used
