title: [A case of metastatic carcinoma of the spermatic cord due to cholangioma].
abstract: Tumor in the spermatic cord is infrequent. Further, among such cases, it is extremely rare to encounter a carcinoma other than a nonepithelial malignant tumor; almost all are metastatic tumors. We recently experienced an interesting case of spermatic cord tumor in a 78-year-old male. He entered our hospital with the chief complaint of a right inguinal tumor. He underwent 2 operations to excise the tumor. The extirpated tumor mass from the right spermatic cord was composed of adenocarcinoma with abundant fibrous stroma, which is considered to be metastasis from the other viscerae. We were unable to find the primary focus in spite of extensive clinical and pathological examinations. In an autopsy about four months after the 2nd operation, the tumor was confirmed to be primary intrahepatic bile duct carcinoma, which is called cholangioma. There have been only 20 cases of metastatic spermatic cord tumor reported in Japan. However, we considered that this is the 1st case caused by cholangioma in Japan and even in other countries.
