Here we present a case of 31-year-old woman diagnosed with primary mesenteric Ewing sarcoma after a prolonged diagnostic course. The patient initially presented with recurrent abdominal pain while she was on treatment for infertility, and subsequent evaluation revealed mesenteric lesions along with venous thrombosis. Histopathologic and molecular analysis confirmed the diagnosis. A review of the literature is included to provide insights into the clinical features, diagnostic approach, and management strategies for this rare entity. Key words: Extra-osseous Ewing sarcoma, soft tissue tumor, mesentery.
