[Quantitative analysis of morphological manifestations of cholesterosis and concomitant pathology of the gall bladder].

Morphological study of 345 cholecytectomies revealed gall bladder cholesterosis in 173 cases. Network form of cholesterosis was most frequent (73.8%), polyposis-network was in 18.5% and only 8.7% polypoid form of cholesterosis was found. The frequency was similar in males and females, the polypoid form prevailed in males, reticular form in females. Main site of cholesterosis was the gall bladder body. Combination of cholesterosis with cholelithiasis was in 151 cases (87.3%), adenomyomatosis occurred in 33 patients (19%). Cholesterol polyps were found in 47 patients, in 30 of them they were multiple. The size of cholesterol polyps varied from 2 to 17 mm. For the first time mixed glandual-cholesterol polyps are described. Morphological picture of xanthogranulomatous cholecystitis was in 7 patients. The morphological difference between foam and xanthome cells is presented.
