<prompt> Which of the following glomerular disease is associated with Crescent formation?Minimal change diseaseRapidly progressive glomerulonephritisFocal and segmental glomerulosclerosisRapidly non progressive glomerulonephritis  <response>: The most common histological picture of Rapidly progressive glomerulonephritis is the presence of crescents in most of glomeruli. Crescents are formed by proliferation of parietal cells and by migration of monocytes and macrophages in the Bowmans space. The prognosis can be roughly related to the number of crescents.
