INTRODUCTION
Primary small intestinal malignancies are rare with an incidence of less than 5% of all gastrointestinal malignancies and are more common in the middle-aged and elderly population. They are comprised either an adenocarcinoma, neuroendocrine tumor, gastrointestinal stromal tumor (GIST), lymphoma, and/or sarcoma.
CASE PRESENTATION
Here we exhibit the case of a 23-year-old who presented with progressive nausea, weight loss, abdominal pain, and iron deficiency anemia and was diagnosed with leiomyosarcoma of the jejunum.
CONCLUSION
We distinguish a GIST from leiomyosarcoma based on radiographic, histologic, and epidemiologic evidence and review the significance of prompt, accurate diagnosis as related to treatment.
引言
原发性小肠恶性肿瘤较为罕见，发病率不到所有胃肠道恶性肿瘤的5%，在中老年人群中更为常见。它们包括腺癌、神经内分泌肿瘤、胃肠道间质瘤（GIST）、淋巴瘤和/或肉瘤。
病例报告
在此我们展示一例23岁患者的病例，该患者出现进行性恶心、体重减轻、腹痛和缺铁性贫血，被诊断为空肠平滑肌肉瘤。
结论
我们根据影像学、组织学和流行病学证据区分胃肠道间质瘤和平滑肌肉瘤，并回顾及时、准确诊断与治疗相关的重要性。
