[Morphologic manifestations of Waldenström's disease].

The authors describe the various cytological and pathological lesions found in lymph node, spleen, bone marrow and liver in Waldenströms macroglobulinemia. The significance of the discovery of PAS positive intranuclear vacuoles is discussed. The findings are completed by a description of the results obtained in immunofluorescence and under the electron microscope. Unusual forms and the differential pathological diagnosis are then discussed.
