Dedifferentiated liposarcoma is a unique subtype of liposarcoma, which has obvious histological heterogeneity. In affected patients, the condition typically manifests as the dedifferentiation of high-grade histological morphology, but it may also manifest as the dedifferentiation of low-grade histological morphology. In some cases, unique histological or immunophenotypic characteristics are observed. We describe, herein, a rare case of dedifferentiated liposarcoma, in which the high-grade and low-grade dedifferentiated components coexisted with a relatively sharp transition in pathology.
去分化脂肪肉瘤是一种独特的脂肪肉瘤亚型，具有明显的组织学异质性。在受影响的患者中，该疾病通常表现为高级别组织形态学的去分化，但也可能表现为低级别组织形态学的去分化。在某些情况下，还观察到独特的组织学或免疫表型特征。我们在此描述了一例罕见的去分化脂肪肉瘤病例，其中高级别和低级别去分化成分共存，病理学上具有相对明显的过渡。
