Abstract

A 73-year-old woman was admitted for further examination of gallbladder mass. Abdominal ultrasonography depicted multiple small elevated lesions. Endoscopic ultrasonography displayed broad-based elevated lesions surrounded by irregular mucosal thickening. Since the outer hyperechoic layer was not disrupted, the tumor was diagnosed as early gallbladder carcinoma and the surgeons performed cholecystectomy with liver bed resection. Macroscopic observation of the resected specimen showed widespread granular mucosa and short elevated lesion. A discolored polyloid lesion about 5 mm in size was located near the main elevated lesion. The pathological findings revealed early gallbladder carcinoma and widespread dysplasia. The polypoid lesion was diagnosed as hyperplastic polyp of pylorus metaplasia, the surface of which was covered by carcinoma. In this present case, a carcinoma and a hyperplastic polyp coexisted in very impressive shape.
