[Mixed cryoglobulinemia-associated membranoproliferative glomerulonephritis, disclosing gastric MALT lymphoma].
We report a case of a mixed cryoglobulinemia-associated membranoproliferative glomerulonephritis, disclosing gastric lymphoma of MALT-type. In the reported case, glomerulonephritis was associated with joint and skin symptoms related to type II mixed cryoglobulinemia. MALT lymphoma diagnosis was made by gastric biopsy. Renal pathological examination showed relatively uncommon findings, ie mesangioproliferative glomerulonephritis lacking usual intraluminal thrombi. Although classical, renal manifestations of malignant lymphomas are uncommon, and rarely allow lymphoma diagnosis. The renal biological function improves as the lymphoma regresses with appropriated treatment. This case underlines the benefit of gastroscopy in cryoglobulinemia etiological research.
