摘要

Plasma cells are terminally differentiated B cells whichnormally secret immunoglobulins. The group of plasmacell disorders consistsof several sub-categories includingmonoclonal gammopathy of unknown significance(MGUS), primary amyloidosis, the polyneuropathy,organomegaly, endocrinopathy, monoclonal gammopathy,and skin changes (POEMS) syndromeas well as multiplemyeloma (MM). The latter category is subdivided intosymptomatic versus asymptomatic myeloma and is alsostratified by clinical prognostic scores such as the oldDurie-Salmon classification and the newer internationalscoring system (ISS), as well as according to reproduciblechromosomal abnormalities and more recently also byhigh versus low-risk gene expression profile (GEP). Theclinical manifestations of transformed plasma cells aremainly derived from the local effects of the tumor cellsproper and from the impact of the circulating monoclonalimmunoglobulins.
