Abstract

We report a case of sarcomatoid carcinoma of the ureter in a 82-year-old woman. She was admitted to our hospital with right hydronephrosis. A computed tomography (CT) and retrograde pyelography (RP) showed a solid tumor at right ureter with right hydronephrosis and 3cm solid tumor on the right abdominal wall. She underwent laparoscopic nephroureterectomy and excision of abdominal subcutaneous tumor. Pathological diagnosis was urothelial carcinoma with sarcomatoid variant, pT3, grade3 and abdominal wall metastasis. Other metastasis occured in left kidney and ileum about 1 month after the operation, and then she underwent laparoscopic partial nephrectomy and ileocecal resection. The histopathological diagnosis was sarcomatoid carcinoma with positive staining for granulocyte-colony stimulating factor (G-CSF). The paient died of multiple metastases 5 months after first operation. As far as we know, this is the first report of G-CSF producing infiltrating sarcomatoid carcinoma of the ureter in Japanese paper.
