<prompt> Examine the renal histopathology slide. What is the probable diagnosis?Membranoproliferative GNRapidly profilerative GNPost streptococcal glomerulonephritisDiabetic nephropathy  <response>: The presence of diffuse involvement of glomeruli and histologically showing enlarged hyper cellular glomeruli is suggestive of Acute infectious GN. It can be both infectious and non-infectious SLE but the most common infectious acute proliferative GN is post streptococcal GN. So, the likely answer is post streptococcal glomerulonephritis.
