Ewing Sarcoma of the Jejunum: A Case Report and Literature Review.

Abstract

Background: Ewing sarcomas (ES) 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 lady came to our hospital after finding out her elevated tumour biomarkers during her physical examination. Her enhanced CT scan showed a jejunal mass. The patient underwent laparoscopic enterectomy. The mass was later diagnosed as Ewing sarcoma, evidenced by Fluorescence In Situ Hybridization (FISH) whereby the GLP EWSR1 probe was used, showing that more than 10% of the cells showed a red-green-yellow signal proving the breakpoint rearrangement of the EWSR1 gene in chromosome 22.Conclusion: We described a case of localised ES at the jejunum, in China, based on literatures.
