Kimura’s disease with membranoproliferative glomerulonephritis: a case report with literature review

Background: Kimura's disease is a rare disease and its etiology is still unclear. Here we reported a case with lymphadenopathy complicated with secondary membranoproliferative glomerulonephritis. Case presentation: A 46-year-old Chinese man presented with bilateral tumor-like nodules over his neck during the past 6 months and developed edema for 15 days. His blood pressure was 145/90 mmHg, multiple 1 × 1 cm masses were found over bilateral post-auricular and submandibular areas, along with trace edema of the lower extremities. Laboratory data showed an increased peripheral eosinophil count at 3.66 × 109/L (50% of total leukocytes), with a 24-hour urine total protein of 8 g and a serum albumin of 19 g/L, and serum IgE of 2930 IU/ml (
