[Renal hemosiderosis following mechanical hemolysis: An original case report].

Renal hemosiderosis is a rare cause of acute kidney injury, but it can also lead to chronic kidney failure. We report here the case of a 73-year-old patient with acute kidney caused by a massive hemosiderosis following the proximal disinsertion of a prosthesis of the ascendant aorta with chronic aortic dissection. The kidney biopsy revealed the diagnosis, showing massive iron deposits inside the proximal tubules, especially with Perls staining and also diffuse hematic casts in the lumen of the tubules.

[Management of idiopathic membranous nephropathy: evaluation of a standardized strategy in a Lorraine health network].

Introduction: The evolution of idiopathic membranous membranous (MNi) is variable, treatment is discussed. Our work's main objective was to evaluate the results of a standardized management strategy proposed in 2006 in Lorraine (Nephrolor health network). The secondary objective was to evaluate the professional practices.

[Renal infiltrate by a plasmocytoïd chronic B lymphocytic leukaemia and renal failure: a rare occurrence in nephropathology. A case report and review of the literature].

We report the case of a 55-year-old male with renal failure as the initial manifestation of interstitial and focal infiltration of the kidneys by a small B-cell lymphoma. Since three years, this patient had a history of CLL with plasmocytic differentiation and was left untreated owing to stade A Binet classification. After chemotherapy, the lymphocytosis and the adenopathies disappear and the renal function improve.

Immunoglobulin deposition disease with a membranous pattern and a circulating monoclonal immunoglobulin G with charge-dependent aggregation properties.

A 62-year-old woman presented with nephrotic syndrome, monoclonal gammopathy, and membranous-like nephropathy with nonorganized deposits composed of monoisotypic immunoglobulin G1 lambda protein. Nephrotic syndrome remitted after a brief course of treatment with melphalan despite ongoing production of the monoclonal protein. The circulating monoclonal immunoglobulin G1 lambda showed unusual in vitro aggregation properties, including dependence on low ionic strength and neutral pH, suggesting that electrostatic interactions had a role in the precipitation process.
