Collecting ducts Collecting duct carcinoma (collecting duct carcinoma - CDC, Bellini duct carcinoma - BDC) arises from the epithelium of collecting tubules of the kidney. It is very uncommon, with the incidence lower than 1% of all renal cancers and about 80 cases reported in literature only. Its occurrence hasn't been published in available Czech and Slovak literature. Case of 26-year old woman with advanced disease of the right kidney is presented. Etiology of kidney enlargement and vena cava thrombosis could not be distinguished by the imaging methods preoperatively. Tumor diagnosis was done in the time of surgery. Radical nephrectomy was performed and unresectable thrombus was left in situ. Two cycles of MVAC chemotherapy were applied based on the histopathological finding. Patient died 13 months after diagnosis by the global cardiovascular decompensation. In differential diagnosis collecting duct carcinoma has to be distinguished from papillary adenocarcinoma which invades the renal medulla and with urothelial carcinoma with invasion to the renal parenchyma.
