<unk>  <unk>  is a morphological pattern characterized by a numerical increase in<unk>  cells and expansion of the extracellular matrix within the mesangium of the glomerulus. The increase in the number of<unk>  cells can be diffuse or local and immunoglobulin and/or complement deposition can also occur.<unk>  is associated with a variety of disease processes affecting the glomerulus, though can be idiopathic. The clinical presentation of<unk>  usually consists of hematuria or nephrotic syndrome. Treatment is often consistent with the histologic pattern of and/or disease process contributing to<unk> , and usually involves some form of immunosuppresant.
