Metastatic melanoma to the common bile duct causing obstructive jaundice: A case report

Figure 1  Showing filling defect within the distal common bile duct causing almost complete obstruction.

Figure 2  A pigmented malignant tumour evidently infiltrates extrahepatic bile duct. Later histochemical and immunohistochemical analyses showed melanoma cells (HE, × 13).

Figure 3  Higher magnification of the same tumour field showed insular and trabecular-to-solid histological organization of melanoma cells. Most of the cells were hyperpigmented with massive intracytoplasmic melanosome granules (HE, × 64).
