Fabry-like laminated myelin body associated with IgA nephropathy.

Abstract

We present the first female patient to exhibit Fabry-like myelin bodies in the glomerular epithelial cell in association with IgA nephropathy. This previously healthy 36-year-old woman presented with proteinuria and hematuria without skin lesions. Renal biopsy showed typical IgA nephropathy, with paramesangial deposits, mesangial proliferation and scattered myelin bodies. The leukocytic alpha-galactosidase A activity was abnormally low. She had no family history of Fabry's disease nor the characteristic features, such as skin lesion, neuralgia, or hypohidrosis. Fabry's disease is diagnosed from the renal biopsy findings and the activity of alpha-galactosidase A in leukocytes and/or fibroblasts. We diagnosed the present case with Fabry' disease and IgA nephropathy from these results.
