Abstract

Rod-like inclusions have rarely been described in cases of monoclonal gammopathy of renal significance or multiple myeloma. The key finding in our case is the strong κ-light chain positivity of rod-like inclusions in plasma cells, which confirms their immunoglobulin nature. Therapeutic benefit of bortezomib was also observed.
