Paraneoplastic Atypical Anti-GBM Nephritis Associated with Diffuse Large B-Cell Lymphoma (KIDNEY WEEK 2026) - Oct 2, 2026 - Abstract #FR-PO1276; Pres time: Oct 23, 2026; 10:00 AM - 12:00 PM; Location: Exhibit Hall A, Convention Center; "Following three cycles of pola-R-CHP (polatuzumab, rituximab, cyclophosphamide, doxorubicin, and prednisone), interval PET/CT demonstrated marked reduction in FDG-avid lymphadenopathy. The absence of circulating anti-GBM antibody and absence of diffuse crescentic phenotype distinguish this from classic anti-GBM nephritis and poses a challenge for monitoring treatment response. This case expands the spectrum of paraneoplastic glomerulopathies in hematologic malignancies and underscores the importance of kidney biopsy in establishing the diagnosis."
