Ewing sarcoma of the jejunum: A case report and literature review

Figure 1 Transverse spiral computed tomography scan of the abdomen, with intravenous contrast enhancement showing dilation of jejunal wall of the left lower quadrant.

Figure 2 Immunohistochemical analysis. A: Low magnification of the resected sample using formalin-fixed (magnification: × 40); B: Paraffin-embedded sections of tumor stained with hematoxylin and eosin demonstrating sheets of small (magnification: × 100); C: Round-to-spindle, uniform tumor cells with clear cytoplasm (magnification: × 200); D: Higher magnification of C (magnification: × 200).

Figure 3 Fluorescence in situ hybridization. A: Fluorescence in situ hybridization of the resected tumor showing more than 10% of the cells showed a red-green-yellow signal, proving the breakpoint rearrangement of the Ewing Sarcoma breakpoint region 1 gene; B: More than 10% of the cells from resected sample showing a red-green-yellow signal (magnification: × 200).

Figure 4 Post-operative bone X-ray which shows no lesion in skeletal system thereby excluding metastasis. A: Anterior-posterior view of the chest; B: Posterior-anterior right upper thigh; C: Posterior-anterior left upper thigh; D: Anterior-posterior right upper thigh; E: Anterior-posterior left upper thigh; F: Anterior-posterior lower leg; G: Anterior-posterior lower leg; H: Medial-lateral lower leg; I: Medial-lateral lower leg.
