Renal histology of case presented. (a) Masson trichrome original magnification (270x) demonstrated diffuse mild thickening of glomerular basement membranes with slight dilatation of the capillary lumens, Mesangial proliferation was not evident on light microscopy. Immunofluorescence showed diffuse and global finely granular deposits of IgG (+++) (b) and C3 (+) along outer aspect of the glomerular basement membranes. There was also a bright mesangial positivity for IgA (+++) and less intense for C3 (++) (c).
