Pathomorphology of porcine polycystic kidney: A case report

A rare form of bilateral autosomal recessive polycystic kidney disease (ARPKD) was observed incidentally in a six month old hybrid Tamworth and Desi crossbred pig during necropsy examination in the Department of Pathology, Ranchi Veterinary College, Ranchi. Grossly, both kidneys showed cystic lesion of varying size all over the renal surface. Dorsal section of kidney showed presence of watery or mucoid content in the cystic cavities with scanty normal renal parenchyma in between cystic lesions. Microscopically, cystic lesions were lined by flattened epithelium indicating their tubular origin along with fibrosis in the interstitium. The end stage renal failure appears to be the cause of death in the present case. The case was diagnosed as a rare porcine polycystic kidney disease(PKD).
