Direct immunofluorescence of a renal biopsy (Anti IgA).

Fibroelastosis of an arcuate artery in Benign nephrosclerosis: Elastic tissue is strongly autofluorescent. The internal elastic lamina of an arcuate artery is shown to be reduplicated many times and seen as parallel undulating brightly fluorescent lines. Reduplication the internal elastic lamina and fibrosis of the wall in arcuate or interlobular arteries constitute what is called fibroelastosis and is a consistent finding in benign nephrosclerosis.[1],[2]

This is usually an incidental finding in renal immunofluorescence and will be found in all sections irrespective of the antibody used.
