plasma cell myeloma
Definition: plasmacytoma of bone, which is usually a solitary lesion and not associated with the occurrence of Bence Jones protein or other disturbances in the metabolism of protein (as observed in multiple myeloma). Some observers emphasize that the solitary lesion probably represents an early phase of classic multiple myeloma, or an example of the latter in which only one focus is recognized.
Synonym(s): multiple myeloma
