去分化脂肪肉瘤的去分化成分有着广泛的组织学变异,这些变异包括肿瘤的异源性分化。已经证实去分化脂肪肉瘤有肌纤维母细胞的分化,但是尚未见去分化脂肪肉瘤酷似炎性肌纤维母细胞肿瘤的报道。作者研究了6例具有炎性肌纤维母细胞肿瘤特征的去分化脂肪肉瘤的临床病理、免疫组织化
Dedifferentiation of dedifferentiated liposarcomas has a wide range of histological variations that include heterogeneous differentiation of tumors. Dedifferentiated liposarcoma has been shown to differentiate myofibroblasts, but no dedifferentiated liposarcoma resembles reports of inflammatory myofibroblastic tumors. The authors studied the clinical pathology, immunohistochemistry of six cases of dedifferentiated liposarcoma with inflammatory myofibroblastic tumor characteristics
