[Localised adenomyomatosis of the gall bladder].

Adenomyomatosis of the gall bladder is a rare benign disease in which hypertrophic mucosa makes deep sinuses into hypetrophic muscular layer making, the so called Rokitansky-Aschoff's sinuses. It appears as a localised, segmental or diffuse form of the disease. Localised adnomyomatosis leads to the formation of "tumorous" lesions. Two patients, a 44-year old man and a 67-year old woman in whom "tumorous" lesions of the gall bladder were diagnosed preoperatively, are presented. Both patients were operated on. Cholecystectomy was carried out. "Tumorous" changes were, in fact, a localised form of adenomyomatosis, what was histologically confirmed.
