Fig. 2From: Minimal change disease associated with gastrointestinal stromal tumor accompanied by significantly elevated serum IgE level: a case reportTumor cells were spindle shaped cells with rod like hyperchromatic nuclei (A). Only one mitose was observed per 50 HPF (HE stain, × 400). The tumor cells were positive for CD117 (× 400) (B), Dog-1 (C) and Vimentin (D), while stains for CD34 (E), smooth muscle actin (SMA) (F), desmin (G) and s-100 (H) were negative. The positive ratio of Ki-67 staining was less than 10% (I)Back to article page
