Figure 5:

Cholesterol polyps were typically found in gallbladders that were devoid of any significant chronic changes. (A) They could be multifocal as seen in this example, though not as frequently as the fibromyoglandular polpys. (B) They had very thin stalks and as a result they commonly were detached from the surface. The main characteristic of cholesterol polyps, even more so than the cholesterol macrophages (lacking in 15% and barely visible in many others), was their distinctive cauliflower architecture. Another consistent finding was the conspicuous lack of epithelial elements in the cores of the polyp.
