Intravascular Large B-Cell Lymphoma Confined to Peritubular Capillaries Mimicking Interstitial Nephritis and Tubular Injury (KIDNEY WEEK 2026) - Oct 2, 2026 - Abstract #TH-PO1113; Pres time: Oct 22, 2026; 10:00 AM - 12:00 PM; Location: Exhibit Hall A, Convention Center; "The patient received an R-COP regimen combined with etoposide and ruxolitinib, but died 1.5 months later. Marked intraluminal accumulation of lymphoma cells can extensively distend PTCs, creating a pseudotubular appearance that mimics tubular injury or interstitial nephritis, particularly in the setting of concurrent infection and inflammatory cell admixture. In cases with diffuse cellular infiltration and significant renal enlargement, early immunohistochemical evaluation is essential to avoid diagnostic delay."
