Core Tip

Core tip: Skin metastasis from internal malignancy is rare, especially from cholangiocarcinoma. The clinical characteristics and prognosis of the metastases are unclear and need to be further defined. We performed a systemic analysis of 30 cases in the English literature from 1978 to 2014 to expand our understanding of this condition. To the best of our knowledge, this is the first comprehensive analysis of cutaneous metastasis of cholangiocarcinoma.
