Chondrocalcinosis may be associated with metabolic diseases such as hypomagnesemia when it occurs in young people. We report here a case with hypomagnesemia due to familial hypomagnesemia with hypercalciuria and nephrocalcinosis (FHHNC) who developed CC during clinical follow-up. To our best knowledge this is the first case of a young patient with CPPD associated with FHHNC.en10.1515/jpem-2013-0254info:eu-repo/semantics/closedAccesschondrocalcinosis (CC)hypercalciuriahypomagnesemiaArticle2805.06.202071371625720051Q2WOS:000353793000037Q4
