Inflammatory/telangiectatic adenomas (from different cases). A: several sections of adenomas showing different aspects. Upper left: hemorrhagic areas in the center of the tumor; lower left: several micronodules (white arrows) in a patient with a large inflammatory/telangiectatic adenoma (not shown); upper right: this massive adenoma is difficult to identify on fresh tissue; the same is more easily identified after fixation (lower right); B, C and insets: typical aspects with obvious telangiectasia and inflammatory infiltrates (B) around thick arteries (C) (HE); D: some ductular reaction is visible on cytokeratin 7 immunostaining; E: CD34 immunostaining highlights capillarized sinusoids around arteries.
