Computed tomography enteroclysis showed a large well-defined heterodense ovoid space occupying lesion measuring 15 x 10 cm with clumped bowel loops seen in right iliac fossa with intraluminal protrusion and exophytic growth pattern, without lymphadenopathy or metastatic disease (Figures 1(a), 1(b) and 1(c)).

CD117 (a proto-oncogene also known as KIT; Figure 2). Cells were found to be negative for CK and LCA immunochemical stains.
Photomicrograph (H&E stain; original magnification x40) showing unremarkable overlying mucosa, submucosa, muscularis propria, and serosa showing infiltration by tumor.
