本文报告六例少见的鼻腔软骨肉瘤,肿瘤可能源于胚胎性软骨残余或骨外间胚叶组织。诊断软骨肉瘤要注意细胞多少,细胞的异型性排列方式三个方面。根据瘤细胞分化程度又将其分高、中、低分化三级。诊断间叶性软骨肉瘤时除了有大量未分化间叶细胞外,要找到软骨岛,本瘤要与软骨瘤,血管外皮瘤鉴别。软骨肉瘤生长缓慢,罕见转移,主要是局部复发,可与局部广泛切除,五年生存率极高。
This article reports six rare rhinochondral sarcoma tumors that may have originated from embryonal cartilage remnants or extraosseous mesenchymal tissue. The diagnosis of chondrosarcoma should pay attention to the number of cells and the arrangement of cells in three ways. According to the degree of tumor cell differentiation, it is divided into three levels of high, medium and low differentiation. In addition to a large number of undifferentiated mesenchymal cells in the diagnosis of mesenchymal chondrosarcoma, chondrocytes need to be found. This tumor should be differentiated from chondroma and hemangiopericytomas. Chondrosarcoma growth is slow, rare metastases, mainly local recurrence, with extensive local resection, five-year survival rate is extremely high.
