Carcinosarcomas of the bladder are rare. We describe three such tumours, including an apparently unique case in which the components comprised liposarcoma and poorly-differentiated transitional cell elements. A second example included chondrosarcomatous elements. These two tumours showed architectural and immunocytochemical features which suggested that they had originated as carcinomas but had subsequently differentiated along both epithelial and mesenchymal pathways. The third tumour contained both carcinoma and osteosarcoma and may represent a collision tumour.
膀胱癌肉瘤很罕见。我们描述了三例这样的肿瘤，其中一例明显独特，其成分包括脂肪肉瘤和低分化移行细胞成分。第二例包含软骨肉瘤成分。这两例肿瘤显示出的结构和免疫细胞化学特征表明，它们起源于癌，但随后沿着上皮和间充质途径分化。第三例肿瘤同时含有癌和骨肉瘤，可能代表一种碰撞瘤。
