Obstructive jaundice due to an intraductal melanoma metastasis.

In a 63-year-old patient with known malignant melanoma, newly developed jaundice was shown, endoscopically and histologically, to be due to an isolated metastasis in the distal common bile duct. The condition was eliminated by implanting, endoscopically, a bilio-duodenal endoprosthesis. This cause of jaundice is unusual, since this condition is generally a consequence of diffuse liver metastasis.
