A rare B-cell non-Hodgkin lymphoma characterized by the presence of small B-lymphocytes, plasmacytoid lymphocytes, and plasma cells, and either non-secreting or secreting IgG or IgA paraproteins. The disease usually involves the bone marrow, sometimes also the spleen or lymph nodes. Patients typically present with symptoms related to anemia. Hyperviscosity, autoimmune phenomena, and B symptoms may also be observed. Mortality is higher as compared to Waldenström macroglobulinemia.

Orphanet records these for the broader condition rather than for this specific form. They are a starting point, not a figure for this subtype — subtypes often differ, and some are defined by being rarer than the condition they sit under.
ICD-10 codes
ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.
