© 2020 The Japanese Society of Toxicologic Pathology. Spontaneous nephroblastomas are uncommon tumors of laboratory rats. This report describes a spontaneous nephroblas-toma with peritoneal metastasis in an 11-month-old, female Sprague Dawley rat. The rat was part of a breeding program and presented 15 days post parturition with clinical signs including tachypnea, dyspnea and abdominal distension. At necropsy, the right kidney was markedly enlarged by an expansile pale-tan to white multinodular mass with extension into the retroperitoneal space, with multifocal variably sized nodules involving the mesentery, and surface of pancreas, liver, uterus, and ovarian bursa. The rat also had severe bicavi-tary effusion. Histologically, the renal par...
