A 70-year-old man was admitted to hospital because the stool guaiac test was positive. Lower gastrointestinal endoscopy revealed advance sigmoid colon cancer. In abdominal computed tomography, magnetic resonance imaging and angiography, multiple small lesions suspected as cysts were recognized in the liver. Ultrasonography showed those lesions as nodules with various echo levels. It was difficult to make a diagnosis of metasatatic lesions or liver cysts. Sigmoidectomy was perfomed, and we found a large number of grayish white or dark green small nodules scattered throughout the liver. Histopathological examination of the resected liver specimen showed von Meyenburg complex without any malignant cells. In cases of von Meyenburg complex coexisting with malignant disease, careful followups are necessary because the early detection of metastatic liver tumor is very difficult to achieve.
