Among the plasma cell dyscrasias, non-secretory myeloma is one of the rarest. This diagnosis is based on the absence of monoclonal proteins in the serum and urine. When serum free light chains are trace and the kappa: lambda ratio normal, clonality may however be established by PCR. We present a case of an oligosecretory myeloma confirmed by PCR, which would have hitherto been classified as non-secretory.
