 We studied the subjects on carcinoma of the gallbladder, that is, macroscopic characteristics, histological criteria and differential diagnoses, mucin and CEA, and histogenesis, using 42 cases of gallbladder carcinomas.

 The great macroscopic characteristic of the carcinoma was villous, papillary and roughly nodular surface of the elevated or flat lesions. Carboxymucin was predominant in the carcinoma. CEA was positive in 82% of the cancer cases. It was positive in 48% of cases with chronic cholecystitis, where it was limited to very small areas of some metaplastic mucosa and immature regenerating cells of proper gallbladder epithelium.

 A great majority of the carcinomas had severe metaplastic change in the surrounding mucosa. However, the precise histogenesis of the gallbladder carcinoma should be studied with early carcinomas or microcarcinomas.
