Fundal Variant Adenomyomatosis of the Gallbladder: Report of Three Cases and Review of the Literature

Adenomyomatosis of the gallbladder (adenomyomas or adenomyomatous hyperplasia) is relatively uncommon tumor or tumor-like lesions that are found in 2% - 5% of all cholecystectomies. They may involve in the fundal localization as a second frequency and have a predilection for the middle and elderly-aged women. Adenomyomas are histologically characterized by epithelial proliferation and muscular hyperplasia of the gallbladder. The chronic irritation is mostly aetiological factor and rarely has malignant potential. In this paper, the authors present the clinicopathological features of three cases with adenomyomatosis of the gallbladder and discuss under the light of current literature because of the rarity of these conditions.
