Mantle cell lymphoma (MCL) is a rare but aggressive form of non-Hodgkin's lymphoma. Involvement of the kidney is an infrequent occurrence in patients with MCL and can be the result of direct infiltration or paraneoplastic glomerulopathy. Proliferative glomerulonephritis, membranoproliferative glomerulonephritis and focal segmental glomerulosclerosis have previously been reported in association with MCL. We report a 55-year-old woman who developed nephrotic syndrome due to biopsy proven minimal change disease (MCD) in association with MCL. Proteinuria decreased with prednisolone treatment and MCD remains in remission without any immunosuppressant after the treatment of the underlying MCL.
