Description
Summary:Abstract INTRODUCTION Adenomas of the biliary tract are uncommon. Gallbladder adenomas are generally smaller than 20 mm in size and can be classified histologically as tubular, papillary, or tubulopapillary. Villous adenoma of gallbladder is extremely rare and is considered as a premalignant condition that eventually progresses to adenocarcinoma via the adenoma–carcinoma sequence. PRESENTATION OF CASE The clinical data including images, surgical specimen and pathological results of this gallbladder adenoma larger than 50 mm were analyzed. This huge gallbladder adenoma had unique imaging appearance, and the pathological examination revealed the lesion to be villous adenoma with mild to moderate dysplasia. DISCUSSION This rare huge villous adenoma of gallbladder had unique images and pathological appearance different from that of huge tubular adenoma of gallbladder and that of adenocarcinoma. CONCLUSION Large villous adenoma of gallbladder is a rare disease with unique imaging appearance and pathological characteristics.
