Waldenstrøm's macroglobulinaemia of the breast detected by colour Doppler ultrasound.

Waldenstrøm's macroglobulinaemia (lymphoplasmacytoid lymphoma) is a low grade B cell non-Hodgkin's lymphoma. The majority of patients present with advanced disease. Lymphoma of the breast is rare and usually arises as part of a disseminated disease process. A case of disseminated Waldenstrøm's macroglobulinaemia is reported in which the breast was involved. The findings using standard mammographic and ultrasound techniques were non-specific and only when colour Doppler examination was performed could an abnormality be detected.
