Case report. Het sarcomatoïde carcinoom van de ureter
摘要
Sarcomatoid carcinoma of the ureter is an extremely rare and highly aggressive malignancy of the urinary tract. In the literature, this condition has been described only sporadically, resulting in a lack of specific guidelines for determining a treatment strategy. The primary treatment appears to be based on radical surgical excision. We present a case of a 73-year-old man with sarcomatoid carcinoma originating from the left ureter, containing both chondrosarcoma and osteosarcoma components.
