Hepatitis B-associated glomerulonephritis (GN) has been recognized for decades. However, only a few cases of IgA nephropathy (IgAN) in a setting of rapidly progressive glomerulonephritis (RPGN) associated with chronic hepatitis B virus (HBV) have been described. Herein, we report the case of a 42-year-old Asian female with a past medical history significant for chronic HBV on entecavir, hypertension, chronic kidney disease, and newly diagnosed breast cancer, who underwent elective bilateral mastectomy and breast augmentation. Post-operatively, she developed non-oliguric acute kidney injury and proteinuria. Renal biopsy revealed active focal crescentic and necrotizing GN with IgA and C3 deposits. Systemic autoimmune-associated and other infection-related GN were ruled out. IgAN in a setting of RPGN associated with chronic HBV was suspected.
