Abstract
The color of the renal lobe of one kidney in a slaughtered pig had faded, and its cortex and medulla were thin. In histological terms, primitive tubules surrounded by a loose mesenchymatous stroma and scattered immature glomeruli were found in the lesion. Immature mesenchymatous cells had proliferated in the stroma. These morphological features led to a diagnosis of porcine focal segmental renal dysplasia.
