title: Multiple cutaneous metastases from hilar cholangiocarcinoma.
abstract: The most common metastatic sites of cholangiocarcinoma are the retroperitoneal lymph nodes, peritoneum, liver and lungs, and cutaneous metastases of cholangiocarcinoma are rare. Although cutaneous metastases of internal malignancies most commonly present clinically as nontender nodules appearing in a particular area of body, other presentations can occur. Cutaneous metastases of cholangiocarcinoma can appear as a solitary tumour at the therapeutic drainage site. We report a 60-year-old man with unusual cutaneous metastases from hilar cholangiocarcinoma, which presented as multiple indurated plaques and papules on the anterior chest.
