Title: Light-chain deposition disease of the kidney: a case report. Author: Darouich S, Goucha R, Jaafoura MH, Zekri S, Kheder A, Maiz HB. Journal: Ultrastruct Pathol; 2012 Apr; 36(2):134-8. PubMed ID: 22471437. Abstract: A 41-year-old man was admitted for evaluation of nephrotic syndrome associated with microhematuria, hypertension, and moderate renal failure. In serum and urine samples, monoclonal IgG-lambda was detected. Bone marrow examination showed normal representation of all cell lines with normal range of plasma cells. Renal biopsy demonstrated diabetes-like nodular glomerulosclerosis. Immunofluorescence failed to demonstrate the presence of kappa or lambda light chains in the kidney. Electron microcopy showed granular electron-dense deposits along the glomerular basement membranes and in the mesangial nodules. The patient was diagnosed as having light-chain deposition disease (LCDD) without evidence of plasma cell dyscrasia. This report was designed to stress the significant challenges that remain in the diagnosis of LCDD-related glomerulopathy. The salient morphological features that help in making an accurate diagnosis are discussed.[Abstract] [Full Text] [Related] [New Search]
