One investigator found that APs maintained for 3-14 days in a fibrin foam matrix showed histological progression into in situ and then invasive carcinoma (Kalus, 1972). This observation provides strong support for the adenoma-carcinoma sequence but unfortunately has not been described in subsequent reports by others. 6. , 1960; Enterline & Arvan, 1967). The latter group demonstrated chromosomal abnormalities consistently in APs: Hyperploidy and structurally abnormal individual chromosomes were more common in the more severely dysplastic or villous tumors.
