title: Primary lung involvement in Waldenström's macroglobulinaemia: report of two cases and review of the literature.
abstract: Pulmonary involvement in Waldenström's macroglobulinaemia (WM) occurs in 3-5% of cases, but lung involvement without bone marrow infiltration is extremely rare. We report 2 patients who presented with bilateral consolidations on chest X-ray and non-specific symptoms and were treated for a long period of time for pulmonary infections until the diagnosis was made by open lung biopsy. Both patients presented high monoclonal IgM in the serum and one also had blood lymphoplasmacytosis. Trephine bone biopsy and bone marrow smears were normal and there was no other site of involvement. Along with the presentation of our patients, we review the literature, discuss some of the possible underlying mechanisms and raise the attention of clinicians to this rare manifestation of the disease.
