General description

Kidney-specific cadherin (Ksp-cadherin) is a novel, kidney-specific member of the cadherin family of cell adhesion molecules. Within the kidney, Ksp-cadherin is found exclusively in the basolateral membrane of renal tubular epithelial cells and collecting duct cells, and not in glomeruli, renal interstitial cells, or blood vessels. Different cadherins, including E-cadherin, cadherin-6, and N-cadherin, have been investigated in renal cell cancers, demonstrating possible correlations of tumor dedifferentiation and the presence of lymph node metastasis with loss of cadherins. Mazal et al. investigated the utility of using Ksp-cadherin to distinguish chromophobe renal cell carcinoma from oncocytoma. He found a membranous pattern of staining in 96% of 30 chromophobe carcinomas, and in only 6% of 31 oncocytomas leading them to conclude that this is a useful antibody in differentiating these two lesions. Shen et al., on the other hand, found Ksp-cadherin positivity in 100% of 13 chromophobe RCCs, and 95% of 20 oncocytomas.

Renal cell neoplasms are presumably derived from different cell types of the nephron. Clear cell and papillary renal cell carcinoma (RCC) are thought to be of proximal tubular origin, whereas oncocytoma and chromophobe RCC are derived from intercalated cells of

Distinguishing renal oncocytoma from chromophobe and other renal carcinomas is essential, considering their differing biological potentials. Although renal oncocytoma is considered a benign tumor, chromophobe renal cell carcinoma has potentially malignant biological behavior. The numerous reported studies on distinguishing these
