Abstract: |
Overall, the reported incidence of paraneoplastic glomerulopathy (PNGN) related to hematologic malignancies is quite rare, with the total number of case reports in the literature only slightly in excess of 200. When compared to myeloid neoplasias, PNGN has been reported relatively more frequently in patients with the lymphoid malignancies, specifically Hodgkin lymphoma (HL), non-Hodgkin lymphoma and chronic lymphocytic leukemia (CLL). Among the lymphoid neoplasia, paraneoplastic minimal change disease and focal segmental glomerular sclerosis (FSGS) are more frequently reported with diseases of the T-cell lineage like HL, whereas paraneoplastic membranoproliferative glomerulonephritis and membranous nephropathy are more commonly reported with B-cell lineage tumors like CLL. Among myeloid malignancies, mesangioproliferative glomerulonephritis is the lesion most commonly reported on renal biopsy, followed by FSGS. The pathogenesis of PNGN with the hematologic malignancies remains poorly defined. © 2020 Elsevier Inc. All rights reserved. |
