Immunohistochemical analysis of the tumor. Sections were stained with anti-SMA (clone 1A-4, 1:100, Dako, Carpinteria, CA), anti-collagen IV (clone CIV22, 1:50, Dako), anti-synaptophysin (clone 27G12, 1:200, Leica, Buffalo Grove, IL), and anti-CD31 (clone JC70A, 1:40, Dako) antibodies. Tumor cells were positive for SMA (a, x200), and collagen IV signal was distributed among tumor cells in a chicken-wire pattern (b, x200). Tumor cells were focally positive for synaptophysin (c, x200). CD31 staining showed faint positivity (d, x200)
