Abstract
An occurrence of multiple carcinoma in both kidneys of a 5-year-old female cynomolgus monkey is described in the present paper. Macroscopically, the kidneys were enlarged with multiple solid and grayish-white masses and cysts mainly in the cortex and outer medulla. Light microscopically, carcinomas showed either tubulopapillary or tubulosolid growth patterns. Carcinoma cells were pleomorphic cuboidal to columnar cells. Cytoplasm was abundant and either granular and eosinophilic or clear, and nuclei were large and vesicular with prominent nucleoli. Electron microscopy revealed the existence of a brush border-like structure on the cell surface of carcinoma cells, suggesting that carcinoma cells arose from proximal tubular epithelial cells. Small foci of tubular epithelial cell hyperplasia and adenomas were also observed independently of carcinomas. There was no evidence of transition from adenoma to carcinoma, and no metastases were detected.
