In the original Kiel classification, this lymphoma was divided into 3 subtypes: (a) lymphoplasmacytic type, characterized by a predominance of mature plasma cells; (b) lymphoplasmacytoid type, in which plasmacytoid lymphocytes predominate; and (c) polymorphic type, with a considerable number of immunoblasts.[1] In the updated Kiel classification, the polymorphic subtype is no longer recognized.[2]
