Idiopathic carpotarsal osteolysis with nephropathy.
Idiopathic carpotarsal osteolysis is characterized by gradual lysis and resorption of bones, occurring mainly on hands and feet. It may be sporadic or hereditary and either form can manifest renal involvement. Nephropathy is seen more frequently and is more severe in the sporadic form. We present herein two new cases of unrelated boys with the sporadic form associated with nephropathy. One of the patients had focal segmental glomerulosclerosis. The other patient revealed isolated proteinuria.
