A case of λ-type IgG myeloma with scrum hyperviscosity, a strong positive Sia test, and few clinical manifestations is described. As the M-component concentration is not excessively high, after study by thin-layer chromatography these phenomena are attributed to the molecular shape and probably (although to a lesser degree) to M-component aggregation. © 1974 by S.
