Core Tip
Core Tip: Proliferative glomerulonephritis with monoclonal immunoglobulin G deposits (PGNMID) is a rare renal disease whose pathogenesis is not fully understood. Due to its complexity, this disease is easy to misdiagnose. We report the case of a young female patient with gross hematuria and foamy urine. Renal biopsy in another hospital suggested mesangial proliferating glomerulonephritis (MsPGN). Her condition did not improve significantly after treatment with glucocorticoids and immuno-suppressants. Recently, repeated renal biopsy at our hospital suggested PGNMID. This case suggests that although PGNMID often occurs in middle-aged and elderly individuals, it cannot be readily excluded in young people with the pathological type of membranoproliferative glomerulonephritis or MsPGN, even when immunofixation electrophoresis is negative. An accurate diagnosis at the earliest stage may minimize the use of glucocorticoids and immunosuppressants.
