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.
一名65岁男性因胆囊隆起性病变前来就诊。腹部超声显示胆囊体部有一个低回声肿瘤，基底较宽。胆囊壁血流最大速度为20厘米/秒。在超声内镜图像上，最外层高回声层不规则，但未中断。我们将该病变诊断为浆膜下层深度的胆囊癌。行胆囊切除术，肿瘤被诊断为胆囊管状腺瘤。p53免疫染色为阴性。基底较宽的胆囊腺瘤很罕见，在此我们报告该病例并进行几点思考。
