[Pulmonary problems associated with lymphoplasmacytic lymphoma (Waldenström's macroglobulinemia)].

A 62-year-old man, known for some years due to lymphoplasmacytic lymphoma, was admitted with progressive dyspnoea. Multiple lung infiltrates were found upon X-ray examination. Because of the suspicion of an infection, a bronchoscopy with bronchoalveolar lavage was performed.

Acute dyspnoea resulting from pulmonary oedema as the first sign of a phaeochromocytoma.

The day after undergoing neck dissection, a 42-year-old woman developed acute dyspnoea due to pulmonary oedema. Measurements with a Swan-Ganz catheter revealed not only cardiac depression but also a greatly increased peripheral vascular resistance: 5,400 dyn x s x cm(-5)/m2. A phaeochromocytoma with acute cardiac failure leading to pulmonary oedema was considered.
