Immunohistochemical analyses. a, b The tumor cells (arrow) revealed cytoplasmic immunoreactivities for melanocytic marker, HMB-45, but negative for epithelial marker, CAM5.2. In normal pancreatic tissue (asterisk), CAM5.2 was diffusely positive, but very confined immunoreactivity was shown for HMB-45. c, d The tumor cells are negative for S-100 and α-smooth muscle actin (α-SMA). Sinusoidal vasculatures were positive for α-SMA
