Bellini duct carcinoma (BDC), originating from the principal cells of the collecting duct of the kidney, accounts for only 1% of renal carcinomas. This lesion is a histogenetically, morphologically and cytogenetically defined entity. We report an eosinophilic variant of BDC. A 71-year old male presented with a tumor in the right kidney. Nephrectomy was performed. BDC (stage pT3a N0 M0 G2, based on UICC classification) was diagnosed. Electron microscopy revealed an abundance of mitochondria. Intranuclear rodlets were seen. Neuroendocrine differentiation was not demonstrated. After a three-year observation period, there are no signs of recurrence or metastases.

A case of sarcomatoid collecting duct carcinoma (CDC) arising in a long-term hemodialysis-associated acquired cystic kidney was reported. A 71-year-old woman with a 21-year history of hemodialysis showed a peritoneal metastatic carcinoma (carcinomatous peritonitis) with an unknown primary site. An autopsy revealed a sarcomatoid collecting duct carcinoma of the right kidney with multicyst formation. In addition to the carcinomatous peritonitis, the tumor metastasized to the lymph nodes and bilateral lung. The primary tumor was composed of both carcinomatous and sarcomatous components, suggesting a high-grade transformation. Carcinomatous tumor cells were positive for epithelial membranous antigen (EMA), cytokeratin, and reactive to soybean agglutinin and peanut agglutinin, whereas the sarcomatous cells were positive for vimentin as well as EMA. Thus, the immunohistochemical and lectin-histochemical analysis confirmed that the tumor originated in the medullary collecting duct. Although CDC is not common in acquired cystic kidney disease patients, attention should be given to the occurrence of high-grade carcinoma of rare histological variant, as well as conventional renal cell carcinoma.
