Gallbladder adenomyomatosis is a benign lesion, characterized by hyperplasia of the gallbladder epithelium alternating with hypertrophy of the smooth muscle layer, in whose thickness there are epithelial projections that can reach the subserosa/adventitia of the organ, causing thickening of the gallbladder wall and possible confusion with neoplasia. The entity has been detected in 2 to 8% of all cholecystectomies and up to 5% of necropsies. It is usually asymptomatic and when it does generate symptoms, they are usually those of coexisting cholecystitis/cholelithiasis. It is more common in adults and very rarely in the pediatric population. An interesting factor is its probable relationship with gallbladder cancer. We present 7 cases of vesicular adenomyomatosis, one of them with epithelial dysplasia, considered a precursor lesion to cancer.
Keywords: Adenomyomatosis, gallbladder, dysplasia, gallbladder cancer.
