The potential value of immuno-isoelectric focusing in the diagnosis and management of solitary plasmacytoma.
Immuno-isoelectric focusing is a highly sensitive method of detecting small quantities of monoclonal protein. We have previously reported the first demonstration of serum paraprotein in non-secretory myeloma using this technique (Sheehan et al. 1985). We now report a case of solitary plasmacytoma where this technique revealed a small concentration of serum paraprotein when conventional techniques failed, and discuss the potential value of focusing in plasma cell dyscrasia, with limited tumor cell mass. focusing in plasma cell dyscrasia, with limited tumour cell mass.
