Abstract:
Ewing sarcoma (ES) is a rare malignancy that typically occurs within the skeletal system but can also develop extraskeletally. Extraskeletal ES typically presents paraspinally, in the limbs, and retroperitoneum. Rarely, it presents as a primary gastric ES. To our knowledge, there are only 13 reports of primary gastric ES, none of which originated in the cardia of the stomach. Increased identification of how extraskeletal ES, specifically primary gastric ES, presents and characterized is crucial for future treatment development and accurate prognosis. We present the case of a 36-year-old man with hematemesis, ultimately found to have primary gastric ES in the cardia.
