Primary extraosseous Ewing sarcomas have also been described in several other organs and locations other than bones, including the pancreas. These tumors have well-defined histological, immunohistochemical, and molecular characteristics.

Desmoplastic small round cell tumors (DSRCTs) of the gastrointestinal (GI) tract are a rare and highly aggressive variant of soft tissue sarcomas, predominantly affecting the abdominal region. These tumors are believed to originate from multipotent mesenchymal stem cells or primitive progenitor cells. They are composed of small round tumor cells associated with prominent stromal desmoplasia, polyphenotypic differentiation, and gene fusion.

Extraosseous Ewing's sarcoma (EES) is a rare form of Ewing's sarcoma that arises outside the bones in soft-tissue structures. It is thought to result from a genetic abnormality involving the fusion of the EWSR1 gene with various partner genes, most commonly the FLI-1 gene. Common symptoms include pain, swelling, and sometimes a palpable mass at the site of the tumor.

- Ewing's extraosseous sarcoma of the genitourinary system is a rare and aggressive cancer, highlighted by a case of a 58-year-old man with a primitive neuroectodermal tumor invading the bladder, whose symptoms included severe pain, dysuria, and significant weight loss.
- The patient underwent several major surgeries, including cystoprostatectomy and nephroureterectomy, but developed neurological symptoms indicating brain metastases post-operation.
- This case emphasizes the need for heightened awareness and advanced diagnostic techniques in rare cancers, recommending a multidisciplinary treatment approach for better outcomes.
