Ewing sarcoma of the jejunum: A case report and literature review

摘要

BACKGROUND Ewing sarcomas(ESs)are highly aggressive malignancy and are predominant in the long bones of extremities of children and young adults with a slight male predilection and rarely presents at extra skeletal locations.CASE SUMMARY A 55-year-old woman came to our hospital after finding elevated tumor biomarkers during her physical examination.Her enhanced computed tomography scan showed a jejunal mass.The patient underwent laparoscopic enterectomy.The mass was later diagnosed as ES,evidenced by fluorescence in situ hybridization whereby the GLP ES breakpoint region 1 probe was used,showing that more than 10%of the cells showed a red-green-yellow signal proving the breakpoint rearrangement of the ES breakpoint region 1 gene in chromosome 22.CONCLUSION We describe a case of localized ES at the jejunum in China based on the literature.
