Figure 2.

Histopathology from a biopsy specimen demonstrates a great quantity of eosinophilic cell suffusion infiltration accompanied by proliferation of spindle cells (hematoxylin-eosin stain). (A) 10× magnification fields under a light microscope. (B) 40× magnification fields under a light microscope. An arrow shows a typical eosinophilic cell. (C) Arrows show infiltration of eosinophilic cells predominantly around the basement membrane of the microvessels in the proliferative tissue.
