A 37-year-old male patient was admitted with generalized edema as the main symptom. A blood test confirmed hypoalbuminemia and hyperlipidemia, and a urine test confirmed severe albuminuria. A renal biopsy was conducted, which revealed a diagnosis of minimal change disease. Although the patient experienced complete remission of minimal change nephrotic syndrome after oral prednisolone and cyclophosphamide treatment, he is readmitted due to bilateral leg edema 5 years later since minimal change nephrotic syndrome was completely cured. The patient is diagnosed with IgA nephropathy. Although the exact mechanisms of IgA nephropathy in this patient remain unclear, this case represents an extremely rare development, and is separate from the remission of minimal change nephrotic syndrome.
