“…A confirmatory diagnosis of ES requires tissue examination at a morphological, immunological and molecular level 5 6 12. The small round cell morphology bears similarities to neuroblastoma, malignant lymphoma, rhabdomyosarcoma, GIST and desmoplastic small round cell tumour.…”

A man in his 40s with no medical history presented with right-sided abdominal and chest pain. A CT scan of the abdomen demonstrated a 7.7 cm heterogeneous mass arising from the second part of the duodenum. Oesophagogastroduodenoscopy confirmed a malignant-appearing duodenal lesion, with biopsy showing features consistent with small cell carcinoma. The patient underwent three cycles of neoadjuvant chemotherapy, followed by elective Kausch-Whipple pancreaticoduodenectomy. A combination of immunohistochemistry and molecular studies confirmed the diagnosis of a rare Ewing’s sarcoma tumour originating from the duodenum with invasion into the duodenal lumen. The patient recovered well from surgery and remains disease-free 18 months following resection.

Ewing sarcomas are rare tumors arising mainly in the bones and the surrounding soft tissues. 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. In this manuscript, we present a case of primary Ewing sarcoma of the pancreas in a 29-year-old patient, and we systematically review the literature on both primary and metastatic Ewing sarcomas of the pancreas, describing their clinicopathological characteristics. We also discuss the differential diagnosis and the treatment of this rare entity.
