case_images: fig1
case_images: Abdominal CT revealed focal mucosal thickening in the middescending colon, as well as dilation and mild mucosal thickening in proximal segments of the colon (Figure 1).

case_images: fig2
case_images: Histopathological examination of the surgical specimen revealed a fissuring ulcer typical for Crohn's disease (Figure 2) but also demonstrated a proliferation of cells with spindle to stellate shaped nuclei, intermixed mast cells, and no appreciable mitotic figures.
case_images: H&E demonstrating SFT with focal invasion of the submucosa at 20 magnification (2x).

case_images: This cell proliferation extended from the subserosa into the muscularis propria and focally into the submucosa at the area of fissuring, ultimately protruding into the bowel (Figures 3 and 4).
case_images: H&E from stricture site with tumor in view (bottom right) at 40 magnification (4x).

case_images: fig5
case_images: The spindle/stellate cells were STAT-6 nuclear positive (Figure 5) and cytoplasmic CD34 positive (Figure 6).
case_images: CD34 stain marking the cytoplasm of the stellate and spindle cells as well as a staghorn vessel at 200 magnification (20x).

case_images: fig6
case_images: The spindle/stellate cells were STAT-6 nuclear positive (Figure 5) and cytoplasmic CD34 positive (Figure 6). Blood vessels are also marked with CD34 (Figure 6).
