Carcinosarcoma is a tumor composed of malignant epithelial and mesenchymal elements, which occurs rarely in the bladder. Although the prognosis of bladder carcinosarcoma is known to be poor the histology of metastatic lesions is not well described. We report 2 cases of bladder carcinosarcoma with pelvic lymph node involvement. Pure sarcomatous metastasis was present in 1 patient and only carcinoma in the other. The histologic composition of metastatic lesions may be of significance in treatment planning in patients with bladder carcinosarcoma.
癌肉瘤是一种由恶性上皮和间充质成分组成的肿瘤，很少发生于膀胱。尽管已知膀胱癌肉瘤的预后较差，但转移性病变的组织学情况尚无详尽描述。我们报告2例伴有盆腔淋巴结受累的膀胱癌肉瘤病例。1例患者出现单纯肉瘤样转移，另1例仅出现癌转移。转移性病变的组织学构成对于膀胱癌肉瘤患者的治疗方案制定可能具有重要意义。
