Abstract    Gallbladder cancer stands out from the gastrointestinal malignancies because of its unique epidemiological characteristics, femininity, difficulty in early diagnosis, and lack of effective treatment. With the gradual maturity and improvement of diagnostic criteria and expert consensus for gallbladder precancerous lesions, overdiagnosis has been avoided. At the same time, some types of invasive carcinoma have been more accurately defined. Pathological diagnosis is the key evidence to determine the character and progression of tumor, which is related to the prognosis of patients and the evaluation of comprehensive treatment options. Accurate pathological diagnosis is very important for the treatment of gallbladder cancer, especially standardized sampling.

Key words: gallbladder cancer, precancerous lesions, malignant epithelial neoplasms,  , pathological features
