Glomerular lesions in lymphomas and leukemias.
Renal lesions in lymphoid malignancies are rare, with most lesions observed in association with Hodgkin's disease. In two large series of patients with Hodgkin's disease, only 0.4 percent had minimal-change lesion whereas 0.1 percent had amyloidosis. The non-Hodgkin's lymphomas and leukemias comprise large and heterogeneous groups with equally diverse renal lesions. As in Hodgkin's disease, the most frequent lesion is minimal-change nephrotic syndrome. Also recognized are rare reports of renal disease associated with the atypical lymphoid proliferations of angioimmunoblastic lymphadenopathy, giant lymph node hyperplasia syndrome, and acquired immune deficiency syndrome. Broad generalizations regarding the pathogenesis of renal disease in these syndromes are difficult, partly due to the paucity and sporadic reporting of such cases. Mechanisms proposed to explain the renal pathologic findings include autologous nontumor antigens, tumor antigens, fetal antigen expression, immune complex deposition, viral antigens, and disordered T cell function.
