The second needle biopsy. a The specimen shows almost the same findings as the previous biopsy (hematoxylin and eosin staining, ×100). b Although slight anisonucleosis and chromatin increase of dilated sinusoids-lining endothelium* was observed, there was no convincing evidence of angiosarcoma (hematoxylin and eosin staining, ×400). c Sinusoidal endothelium (arrows) was negative for CD34 immunostaining.
