This paper describes a nephroblastoma with transcoelomic metastasis in a three-year-old Japanese black bull. At necropsy, a huge, oval neoplastic mass containing the residual right kidney was found. Moreover, severe transcoelomic metastasis occurred throughout the abdominal and thoracic cavities. Histologically, the mass was mainly composed of sheets, nests, islands and cords of polygonal blastemal cells with trabeculae of fibrous stroma. In some areas, epithelial elements composed of tubules and winding duct-like structures were also observed. Glomeruloid structures were scattered in these epithelial elements. Metastatic nodules were composed of blastemal and stromal elements, which were similar to those in the mass.
