Ewing's sarcoma (ES) is the second most common primary bone malignancy of childhood, whereas extraosseous ES (EES) is more common in older patients. EES of the small intestine is an extremely rare disease. We present a case of ES of the small intestine with liver metastasis mimicking a gastrointestinal stromal tumor. The diagnosis of ES requires a combination of histological, immunohistochemical, and molecular techniques. Further studies to investigate whether multimodality treatments can improve the survival of metastatic EES are needed.
