Renal cell carcinoma in association with IgA nephropathy in the elderly.

摘要

IgA nephropathy can occur as a paraneoplastic syndrome of renal cell carcinoma. We report 3 cases of IgA nephropathy associated with renal cell carcinoma in the elderly patients and demonstrate that infiltrating lymphocytes and plasma cells around renal cell carcinoma produce IgA that likely contributed to mesangial IgA deposition.
