Polyps that are symptomaticand/or greater than 10 mm are generally removed,while smaller, asymptomatic polyps simply monitored.Here, a case of carcinoma-in-situ is presented in a 7mm gallbladder polyp. A 25-year-old woman, who hadundergone a routine cholecystectomy, was found tohave an incidental 7 mm polyp containing carcinomain situ . She had few to no risk factors to alert to hercondition. There are few reported cases of cancertransformation in gallbladder polyps smaller than 10 mmreported in the literature. The overwhelming consensus,barring significant risk factors for cancer being present,is that such lesions should be monitored until theybecome symptomatic or develop signs suspicious formalignancy. In our patient＇s case this could have ledto the possibility of missing a neoplastic lesion, whichcould then have gone on to develop invasive cancer. Asgallbladder carcinoma is an aggressive cancer, this mayhave led to a tragic outcome. 收起
