Wilsons disease (WD) is a rare autosomal-recessive disorder characterized by a mutation in the ATP7B gene, located on chromosome 13, which encodes a protein involved in the metabolism of copper.
We described the case of an Indian male with a history of polydipsia and polyuria, related to hypercalciuria and consequent nephrocalcinosis. The symptoms began at the age of five years old, but he was not diagnosed with WD until he reached an adolescent age. We started therapy with D-Penicillamine, B-vitamin complex and recommended a low copper diet. Renal involvement in Wilsons disease, characterizing by hypercalciuria, was firstly reported by Litin in 1959.
Our case was different and peculiar from the previously described cases because the patient presented a very long history (10 years) of permanent hypercalciuria without any acute episode of nephrolithiasis.
