Cholesterolosis refers to an accumulation of cholesterol-laden macrophages within the mucosa of the gallbladder wall. Gross examination shows yellow speckling of the red-tan mucosa (“strawberry gallbladder”). Microscopic examination shows lipid-laden macrophages within the lamina propria.
Hydrops of the gallbladder (mucocele) occurs when chronic obstruction of the cystic duct leads to the resorption of the normal gallbladder contents and enlargement of the gallbladder by the production of large amounts of clear fluid (hydrops) or mucous secretions (mucocele).
