摘要 目的探讨纵隔低级别纤维黏液样肉瘤(low-grade fibromyxoid sarcoma,LGFMS)的临床病理特征、诊断、鉴别诊断。方法收集1例纵隔LGFMS临床资料,对其临床表现、影像学特点、组织学特征、免疫表型、FUS基因检测及预后进行分析,并复习相关文献。结果肿瘤细胞呈短束状、交织状或漩涡状排列,细胞核呈圆形、卵圆形,核仁不明显,异型性不明显,部分区域可见不同程度的黏液样变,其间可见小分支样血管。免疫表型:vimentin、MUC4均阳性。FISH检测显示FUS基因断裂。结论发生在纵隔部位的LGFMS临床较为罕见,免疫组化标记MUC4联合FISH检测有助于LGFMS的诊断。
