Coexistence of systemic lupus erythematosus, Hashimoto's thyroiditis and IgA nephropathy in the same patient.

Autoimmune disorders encompass a wide spectrum of diseases that progress with several clinical findings. They can be organ-specific (such as Hashimoto's thyroiditis) or they can involve multiple organs (such as SLE). The common characteristic of all these disorders is the production of different autoantibodies against various autoantigens along with inflammation. IgA nephropathy is the most common non-lupus glomerulopathy. It rarely coexists with SLE and has never been reported to coexist with Hashimoto's thyroiditis. In this case report, a female patient diagnosed with SLE and Hashimoto's thyroiditis and whose renal biopsy revealed IgA nephropathy is presented.
