Fig 1 (A) The tumor showed interwoven bundles of spindle cells and diffuse infiltrates of epithelioid cells (left field) with abundant cytoplasm and irregular nuclei. The infiltration of leukocytes was frequently found in the tumor. (B) Intense granulocyte-colony stimulating factor (G-CSF) immunoreactivity was found in the cytoplasm of many tumor cells. (C) More abundant immunoreactivity for G-CSF receptor was recognized in the cytoplasm of tumor cells and endothelial cells. ([A]: hematoxylin-eosin; [B]: immunohistochemistry for human G-CSF; and [C]: immunohistochemistry for human G-CSF receptor.)
