Benign neoplasms of the gallbladder occur so rarely that even in a large surgical practice one encounters few of them; for this reason all studies of these growths have been based on only a few cases. We wish to present a clinical and pathologic study of the benign tumors of the gallbladder encountered at operation at the Mayo Clinic from Jan. 1, 1906, to Dec. 31, 1938, inclusive. The group comprises 45 gallbladders containing one or more polypi, 103 containing adenomyoma and 2 containing fibroma. All the specimens except 3 were obtained by cholecystectomy; 3 were taken for biopsy—2 of the 3 at cholecystostomy and 1 at gastric resection for carcinoma of the stomach. Papilloma of the gallbladder, as has been pointed out by MacCarty,1 by Phillips,2 and by Graham, Cole, Copher and Moore,3 is not a true neoplasm and hence was not included in this study.
