Dense deposit disease: An ultra-rare c3 glomerulopathy in children

Dense deposit disease (DDD), previously known as membranoproliferative glomerulonephritis type 2, is an extremely rare disease affecting two to three people per million. The rarity of this disease makes it difficult for clinicians to establish evidence-based clinical practices for its management. Here, we report a case of DDD who presented with features of acute nephritic syndrome and did not respond to most of the treatment options available in literature.
