Simultaneous occurrence of IgA nephropathy and sarcoidosis in the context of pre-existent minimal change nephrotic syndrome.

Simultaneous occurrence of IgA nephropathy and sarcoidosis is described in a 42-year-old Asian female, who earlier had a steroid-resistant, no light microscopy change nephrotic syndrome that resolved spontaneously. Occurrence of three, apparently unrelated conditions in this case may be fortuitous, or causally related. We discuss the possible causal relationship amongst these conditions.
