摘要
We report on a 36-year-old man who presented to the emergency department with haemoptysis. Computed tomography (CT) of the thorax showed a pulmonary mass paramediastinal in the right upper lobe, with the density of a haematoma. Laboratory data demonstrated an absolute lymphocytosis of 5.900 x 10(9)/l (normal range, 1.150-3.250 x 10(9)/l) and a prolonged activated partial thromboplastin time (APTT) of 47.7 s (normal range, 28.0-39.0 s). A de novo diagnosis of lymphoplasmacytic lymphoma (Waldenstrom macroglobulinaemia) was made, complicated by an acquired von Willebrand syndrome (aVWS) as demonstrated by further laboratory investigations. In this case report, we present a case of aVWS with markedly prolonged APTT and haemoptysis that revealed an underlying Waldenstrom macroglobulinaemia.
