[Primary sarcomatoid carcinoma of the ureter]. / Primäres sarkomatoides Karzinom des Ureters.

ABSTRACT

INTRODUCTION: We present a case of unusually rapid tumor progression in a patient with primary sarcomatoid carcinoma of the ureter. CASE REPORT An 82-year-old female patient underwent total nephroureterectomy for a ureteral tumor that turned out to be a primary sarcomatoid carcinoma of the ureter. After a normal postoperative course, the patient developed a metastatic symptomatic that seemed to have appeared "like an explosion" on the 33rd p. o. day. She died shortly thereafter. CONCLUSION: This is the second case of primary sarcomatoid carcinoma of the ureter published in the literature, a rare and aggressive variant of urothelial carcinoma with a highly malignant potential. As no effective adjuvant treatment has been reported as yet, we recommend mandatory radical excision of the sarcomatoid tumor and early postoperative radiation therapy to increase survival.
