Malignant phyllodes tumor is usually diagnosed by the presence of benign duct-like epithelium and malignant mesenchymal tissue. In addition to the usual fibrosarcomatous features, the mesenchymal component may show areas resembling osteogenic sarcoma, chondrosarcoma, liposarcoma, leiomyosarcoma, rhabdomyosarcoma, malignant mesenchymoma, and, very rarely, malignant fibrous histiocytoma. We present one such rare case of malignant phyllodes tumor with malignant fibrous histiocytoma-like stromal differentiation.
恶性叶状肿瘤通常通过良性导管样上皮和恶性间充质组织的存在来诊断。除了常见的纤维肉瘤特征外,间充质成分可能显示出类似骨肉瘤、软骨肉瘤、脂肪肉瘤、平滑肌肉瘤、横纹肌肉瘤、恶性间叶瘤的区域,并且非常罕见地显示出恶性纤维组织细胞瘤的区域。我们报告了1例这样罕见的具有恶性纤维组织细胞瘤样间质分化的恶性叶状肿瘤病例。
