恶性间叶瘤,是罕见的软组织恶性肿瘤,可发生于各种年龄和各个部位,下肢是好发部位,男女发病比率无大差异,临床无特殊症状,肿瘤大小不一,预后视其瘤内主要的间胚叶成份,如分化好脂肪肉瘤,其预后较好,较少转移,但术后复发较多。本病国内极少报道,我院曾收治1例,现报道如下。 Malignant mesothelioma is a rare soft tissue malignancy that can occur at various ages and sites. The lower extremity is a predilection site. There is no significant difference in the incidence rate between males and females, there are no clinically specific symptoms, and the tumor sizes are different. The prognosis is considered intratumoral. The main mesenchymal components, such as liposarcoma differentiation, have a good prognosis and less metastasis, but more recurrence after surgery. The disease is rarely reported in the country. One case was treated in our hospital. The report is as follows.
