    Abstract:
    This is a report of a case of Bellini duct carcinoma of the kidney. A 72-year-old male was admitted to our hospital for the treatment of left renal tumor. The abdominal computed tomographic scan showed hypoattenuating tumor with infiltrative spread into the renal cortex. The renal angiography revealed a hypovascular tumor. Left nephro-ureterectomy was performed because transitional cell carcinoma was suspected in the frozen section. The gross examination revealed an infiltrating white-gray tumor centered in the renal medulla. No hemorrhage was discovered, but partial necrosis was found. Capsular infiltration was not seen. Histologically, tumor cells were mostly scattered and partially showed a papillary and tubular structure. Cells had abundant eosinophilic cytoplasm and large irregular nuclei. Immunohistochemical studies revealed positive reactions for cytokeratin, epithelial membrane antigen and ulex europaeus agglutinin. We diagnosed this patient with Bellini duct carcinoma. He died due to drastic progression of metastasis from carcinoma two months postoperatively.
