A Formalin fixed cholecystectomy specimen with lumens exposed. Conjoined gallbladders 1 and 2 (left and center) showed typical tan velvety biliary type mucosa, whereas attached mass lesion (right) notable for luminal gastric features; pale coarse rugal folds. B Hematoxylin and eosin (H&E) stained microscopic section (20X magnification) demonstrating back-to-back walls of conjoined gallbladders 1 and 2 with typical biliary type mucosa. Mural thickening is present indicating chronic cholecystitis. C Vast majority of separately attached lesion lined by oxyntic (body/fundal) type gastric mucosa (H&E, 100X magnification). Microscopic images obtained using Olympus® BX43 microscope with Olympus® DP27 camera and Olympus® cellSens Entry 2.3 (Build 18,987) image processing software
