Small cell lung carcinoma presenting as acute cardiovascular collapse due to tumour cell embolisation

We present a case of small cell lung carcinoma causing acute cardiovascular collapse due to pulmonary tumour emboli. Although pulmonary tumour emboli may complicate a number of malignancies, this is rarely seen in cases of ca rcinoma of the bronchus. Patients suffering with pulmonary tumour emboli of ten have previous symptoms, and show progressive dyspnoea. To our knowledge there have been no reports of tumour emboli presenting acutely without any previous history of symptoms. Copyright (C) 2000 S. Karger AG. Basel.
