IgA nephropathy associated with erythrodermic psoriasis: A case report.

Cases about IgAN associated with EP are rare and the pathogenesis is poorly understood. We reported a 74-year-old Chinese male who suffered the IgAN and EP at the same time and explored a possible pathophysiologic link and points toward the possible pathogenesis.The patient complained deteriorating symptoms (erythrodermia, skin pruritus, and pain) of psoriasis and obvious pitting edema on his legs.The patient was diagnosed as IgAN and EP concurrently according to medical history, physical examination, laboratory test, and pathology.Intravenous dexamethasone (5 mg/day) and oral ciclosporin (200 mg twice a day).The patient's symptoms of psoriasis and IgA nephropathy improved obviously after 11-day treatment and discharged from the hospital.IgAN should be considered when the patient is diagnosed as EP. The combination of dexamethasone and ciclosporin may be effective option for patients with IgAN and EP concurrently.
