The clinicopathological study of 37 cases of adenomyomatosis (localized type) of the gallbladder is described. There were 21 male and 16 female patients. Their ages ranged from 33 to 88 with an average age of 57.2 years. The cholecystographic examination revealed a round or semilunar-filling defect in the fundus in only five cases. The lesions were located in the fundus and appeared macroscopically as a circumscribed, sessile nodule with or without a central umbilication. Their sizes ranged from 7 to 17mm in diameter on histologic sections. The microscopic features of the lesions were basically composed of glandular structures and bundles of connective tissues and smooth muscles. In the mid-portion of the lesions, tissue sections showed villous mucosal hyperplasia and adenomyomatous lesions within the muscle layer and subserosal layer. In the peripheral portion, on the other hand, they revealed only adenomyomatous lesions within the subserosal layer.Cholecystectomy was carried out in 37 cases. All patients have been doing well since surgery.
