To the casuistry of benign tumors of the gallbladder

Benign neoplasms of the gallbladder are extremely rare (according to Finkelstein in 1 % of all surgically treated cases) and are detected, almost as a rule, accidentally during operations or autopsies. Most often, papillomas are observed in the gallbladder, which sometimes degenerate into cancer (P e ls-Leusden, HruSka, etc.); about 15 cases of them are described in the European literature. Fibroids, fibromyomas, fibroids, fibromyomas, papillary fibroepitheliomas, subserous lipomas, adenomas, cystadenomas and adenomyomas are much less common. The etiology of these neoplasms is still unknown: according to a number of authors (Savy, Maya, Finkelstein, etc.), the possibility of their development as a result of chronic rupture of the bladder wall by stones or infection is not excluded. Clinically benign tumors of the gallbladder quite often occur under the guise of chronic, recurrent cholecystitis or cholelithiasis.
