Extraosseous Ewing Sarcoma Manifesting as an Acute Abdomen in a Young Adult Male: a Case Report.

Abstract

Ewing sarcoma is a tumor primarily affecting children and young adults, and usually affects long bones. Extraosseous Ewing sarcoma (EES) is a rare primary tumor of soft tissues. We present a case of abdominal EES with metastasis to thoracic cavity, which presented as abdominal pain and vomiting in a 21-year-old previously healthy gentleman.
