Abstract
INTRODUCTION
Ewing sarcoma most commonly arises in bones but rarely presents in extraskeletal locations. We report one such case arising from the jejunum.
CASE PRESENTATION
A 67-year-old woman presented with acute-onset, right lower quadrant pain. Computed tomography results showed a large mass within the midjejunum with pneumoperitoneum. Surgical excision was performed, and an extraskeletal Ewing sarcoma of the jejunum was suspected histologically. The diagnosis was confirmed with fluorescence in situ hybridization studies.
CONCLUSION
This case emphasizes the importance of recognizing this rare presentation in the small intestine to broaden the differential diagnosis of adult intraabdominal tumors.
摘要
引言
尤因肉瘤最常发生于骨骼，但很少出现在骨骼外部位。我们报告了一例发生于空肠的此类病例。
病例介绍
一名67岁女性因突发右下腹疼痛就诊。计算机断层扫描结果显示空肠中段有一个大肿块并伴有气腹。进行了手术切除，组织学检查怀疑为空肠骨骼外尤因肉瘤。荧光原位杂交研究证实了诊断。
结论
该病例强调了认识小肠这种罕见表现对于拓宽成人腹腔内肿瘤鉴别诊断的重要性。
