A 60-year-old man was admitted for occult fever and a liver tumor detected by ultrasonography. He has a history of penile cancer five years previously. Computed tomography demonstrated a low-density tumor 5 cm in diameter in the right lobe. Angiography showed that the tumor was hypovascular. An aspiration tumor biopsy was performed because of difficulty in diagnosing the tumor, and the pathological findings suggested squamous cell carcinoma, a metastasis of the penile cancer. At surgery the liver tumor was found to have invaded the transverse colon, and right hepatic lobectomy with hilar lymphadenectomy combined with right hemicolectomy was performed. The final pathological diagnosis of the liver tumor was poorly differentiated cholangiocarcinoma. The mechanism of tumor invasion to the colon may have been inflammatory adhesion and penetration of the adjacent transverse colon. Intrahepatic cholangiocarcinoma with invasion of other organs is reported to have a poor prognosis, and it requires strict follow-up.
