A 65-year-old man was referred for a gallbladder elevated lesion. Abdominal US showed a hypoechoic tumor with wide base at the gallbladder body. The maximum velocity of the gallbladder wall blood flow was 20 cm/s. The outermost hyperechoic layer was irregular, but not disrupted on EUS images. We diagnosed the lesion as gallbladder carcinoma with the depth of subserosa. Cholecystectomy was performed and the tumor was diagnosed as tubular adenoma of the gallbladder. The p53 immumostaining was negative. A gallbladder adenoma with wide base is rare, here we report this case with the several considerations.

Background: Gallbladder cholesterol polyp (GCP) and gallbladder adenoma (GA) are easily confused in clinical diagnosis. This study aims to establish a nomogram prediction model for preoperative prediction of the risk of GA patients.
Study Design: We retrospectively collected clinical data of GCP or GA patients who underwent laparoscopic cholecystectomy (LC) between January 2020 and April 2023.

There are several types of microvasculature supplying neoplasms: "newly formed blood vessels" (neoangiogenesis), which are a component of the tumor microenvironment (TME) of invasive carcinoma with wound healing-like reaction; and "pre-existing blood vessels", which are used as tumor-supplying vessels by neoplasms (co-option vessels) and are likely to develop in hypervascularized organs. We herein review the microvasculature of neoplasms of biliary tract with reference to pre-existing vessels and vessel co-options. In the hepatobiliary system, intrahepatic large and extrahepatic bile ducts (large bile ducts) and the gallbladder as well as hepatic lobules are highly vascularized regions.

Background Data regarding the frequency of development of gallbladder pathologies in patients with colon polyps are quite limited and heterogeneous. Hence, this study aimed to investigate whether colon polyps cause an increased risk of developing gallbladder pathologies and the necessity of ultrasonographic screening. Methodology This retrospective, cross-sectional study was conducted among adult patients who underwent a colonoscopy and hepatobiliary ultrasound as part of their health check-up from January 2018 to January 2023.
