The term immunocytoma from the Kiel classification has been mainly used in the European literature and is synonymous with small lymphocytic-plasmacytoid lymphoma in the Working Formulation and with lymphoplasmacytoid lymphoma in the revised European-American Lymphoma (REAL) classification.
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.
