#964 Ewing Sarcoma a Dangerous Pitfall for Poorly Differentiated Neuroendocrine Carcinoma (PDEC) in Ileum

Introduction: Ewing sarcoma (ES) primary to the ileum (IES) has rarely been documented, and shows close similarities in histology and clinical presentation with PDEC.EWSR1-FEV translocation is exceedingly rare in ES, as FEV expression is restricted to prostate, brain, and serotonin neuroendocrine cells (NE) and related tumors.

#942 Ileal Neuroendocrine Well-Differentiated Tumors: Prognostic factors with Focus on Loss of Succinate Dehydrogenase (SDHB) Expression

Introduction: Ileal Neuroendocrine Well-Differentiated Tumors (INWDT) are the most common neuroendocrine neoplasms in the gastrointestinal tract. Gene mutations of SDH complex drive pathogenesis of cancer cells through their role in angiogenesis and cell proliferation.

#646 Immunohistochemical (IHC) and Cytogenetic Approach for Improving Diagnosis and Therapy of Ewing Sarcoma (ES)/pPNET Arising in the Ileocecal Region

Introduction: ES/pPNET primary to the ileocecal region (IpPNET) have been rarely reported on and show close similarities in histology and clinical presentation with small round blue cell tumors. The EWS gene is fused to four members of the ETS family.
