title: [Collecting duct carcinoma (Bellini duct carcinoma) of the kidney with tumor extension into the inferior vena cava].
abstract: We report a case of collecting duct carcinoma (Bellini duct carcinoma) of the left kidney accompanied with a tumor thrombus in the inferior vena cava and the lymph node metastasis. A 69-year-old male presented with gross hematuria and left flank dullness. Computed tomography revealed an isodensity tumor in the left kidney with tumor extension into the inferior vena cava and the regional lymph node swelling. The T1-weighted magnetic resonance image displayed a slightly heterogeneous low-intensity-mass. Renal angiography revealed a hypervascular tumor. We performed left radical nephrectomy with tumor thrombectomy and regional lymphadenectomy. Histopathological examination revealed a collecting duct carcinoma (pT3bN1M0V2a). Seven months after surgery, multiple metastates in bone and liver developed. Then we performed systemic chemotherapy consisting of methotrexate and cisplatin. However, the patient died from the carcinoma 10 months postoperatively.
