General Gross Description
•Characterized by abnormal deposition of mixtures of
cholesterol and triglyceride in macrophages in the
lamina propria of the gallbladder.
•The accumulating macrophages cause a distinctive bulge
and lift the superficial epithelium overlying them.
•The condition can either be localized or extensive and
diffuse.
•The latter is referred to as a "strawberry gallbladder".
•In a strawberry gallbladder, the mucosa tends to be red,
and is flecked with numerous yellowish spots.

foamy macrophages lying just beneath the columnar
epithelium of the gallbladder.
