Description
Summary:Abstract Malignant melanoma is the 19th leading cause of cancer worldwide. It is an aggressive neoplastic disease in which pathophysiological understanding and management has been in constant evolution in recent decades. The primary site is the skin, uvea and mucous membranes and has the capacity to metastasize to any organ. There are few reports of primary or secondary involvement of the biliary tract. We present the case of a 73-year-old woman with a bile duct lesion suggestive of cholangiocarcinoma and a final diagnosis of a single melanoma metastasis. Surgical treatment was performed due to oligometastatic stage IV melanoma with possibility of R0 resection followed by immune checkpoint therapy.
