Polycystic kidney disease (PKD) is characterized by multiple cysts within the renal parenchyma and is acommon heritable disease in humans, dogs, and cats. However, a few cases of PKD have been described in captivepygmy hippopotamuses. Bilateral PKD was observed in a 33-year-old, 198-kg female pygmy hippopotamus duringits necropsy in Seoul Zoo on 15 January 2013. The diagnosis of PKD was confirmed by gross findings andhistopathological examination. One kidney was slightly enlarged, and the lower portion of other kidney contained alarge cyst filled with light yellow, watery fluid. Both kidneys had numerous, variably sized fluid-filled cysts of 2 to20 mm in diameter. Considerable portions of the renal cortex and medulla were replaced by cysts. Microscopic inspectionshowed that the cysts were lined with low cuboidal to flat epithelial cells. The present case report of PKD in a pygmyhippopotamus is the first in Korea.
