摘要

最近的文献报道了一些软组织肿瘤，这些肿瘤携带复发性 YAP1::MAML2 融合，具有上皮样形态，与肌炎性成纤维肉瘤（MIFS）相似。在最近的一系列研究中，这些肿瘤具有阳离子外观和中心坏死，被称为 MIFS 的结节性坏死变异型。但它们与 MIFS 的确切关系及其生物学行为似乎还不清楚。我们报告了一种YAP1::MAML2融合阳性、形态类似MIFS的结节性坏死性肿瘤，并对文献进行了综述。

YAP1::MAML2 Fusion Positive Epithelioid Soft Tissue Neoplasms: A Case Report and Review of the Literature.

In the recent literature soft tissue neoplasms which harbor a recurrent YAP1::MAML2 fusion and have an epithelioid morphology with resemblance to myxoinflammatory fibroblastic sarcoma (MIFS) have been reported. In a recent series these tumors had a nodular appearance and central necrosis and were termed nodular necrotizing variants of MIFS. But their exact relationship to MIFS and their biological behavior seem to be unclear. We report a YAP1::MAML2 fusion positive nodular and necrotizing tumor with a MIFS-like morphology and provide a review of the literature.
