Figure 7:

Dysplastic type changes in a cholesterol polyp. This polyp shows the distinctive cauliflower pattern of a cholesterol polyp. The epithelium shows atypia that is substantially different than the normal epithelium that typically covers a cholesterol polyp. No substantial injury changes are noted to attribute the atypical changes to. This was classified as dysplasia in the original report, and was also classified as low-grade dysplasia also in this study although the precise nature of this process remains to be determined. No high-grade dysplasia or carcinoma is seen (and it was not seen in any of the other cases either).
