n.[肿瘤]脂肪肉瘤
These tumors are known as dedifferentiated liposarcomas.───这样的肿瘤被称为去分化的脂肪肉瘤。
biologic behavior of liposarcomas in the posterior mediastinum seems to correlate well with the histologic subtype and mirrors that of their counterpart in the retroperitoneum.───后纵膈脂肪肉瘤的生物学行为似乎与组织学亚型高度相关，与腹膜后脂肪肉瘤一致。
Pleomorphic liposarcomas, pleomorphic undifferentiated sarcomas, and pleomorphic rhabdomyosarcomas belong to this group.───多形性脂肪肉瘤，多形性未分化肉瘤以及多形性横纹肌肉瘤都属于这个群组。
The liposarcomas contain a variable amount of fat, and both teratomas contain a large amount of fat, and schwannoma, a small amount of fat.───这些脂肪肉瘤含有不等量的脂肪，畸胎瘤含有大量的脂肪，神经鞘瘤含有少量的脂肪。
Dedifferentiated liposarcomas are not unique to the retroperitoneum.───腹膜后并不是去分化脂肪肉瘤发生的唯一部位。
There has been no report in the literature of chest wall liposarcomas presenting as multifocal tumors.───在文献回顾中，不曾有过类似的多发性胸壁脂肪肉瘤的报告。
They are presumed to evolve from the pre-existing well differentiated liposarcomas.───它们被认为是在已有的分化良好型脂肪肉瘤的基础上发展而来的。
CT Diagnosis of Primary Retroperitoneal Liposarcomas───原发性腹膜后脂肪肉瘤的CT诊断
These tumors are known as dedifferentiated liposarcomas.
We present a rare case of multifocal liposarcomas that originated in the chest wall. A 61-year-old woman palpated a mass lesion in her left chest wall, at the subclavicular area.
A minority of retroperitoneal liposarcomas may, either at the time of initial diagnosis or at the time of local recurrence, contain nodule(s) of non- lipogenic sarcomatous elements.
However, retroperitoneal well- differentiated liposarcomas are slow-growing, very large, not encapsulated and very difficult to resect completely due to infiltrative borders.
