[Fabry's disease--late diagnosis in men with chronic nephropathy and skin changes].

We report a case of Fabry's disease, diagnosed in a 39-year-old patient treated for 4 years because of glomerulonephritis. The disease manifested itself by the presence of typical petechiae-like skin lesions in the bathing trunk area (angiokeratoma), eye changes, paresthesia, and--in additional investigations--mild proteinuria, lowered creatinine clearance, along with changes in the central nervous system. A biopsy of the kidney revealed the presence of foamy cells in all glomeruli, and in electron microscopy multilamellar bodies (zebra bodies). The diagnose of the disease was confirmed by a marked decrease in leucocyte alpha-galactosidase activity. An early diagnosis of non-inflammatory character of Fabry's disease allows to avoid an unnecessary immunosuppressive treatment.
