Biopsy proven evolution of post streptococcal glomerulonephritis to rapidly progressive glomerulonephritis of a post
Abstract:
A 15 year old boy with chronic impetigo was admitted with severe acute oliguric renal failure requiring temporary dialytic treatment. Renal biopsy revealed typical diffuse and proliferative glomerulonephritis of the poststreptococcal type. Subsequently high temperature developed with flank pains at the biopsy site, concomitantly with deterioration of renal function. On exploration, a sterile perirenal hematoma was found and a wedge renal biopsy revealed crescentic rapidly progressive glomerulonephritis of the post infectious type. Deterioration to end stage renal failure occurred within a few months. Although universally accepted, biopsy proven evolution from diffuse proliferative and exudative glomerulonephritis to crescentic form of post streptococcal glomerulonephritis has been rarely reported.
