Key result
Asymptomatic small cell lung carcinoma can present as acute cardiovascular collapse from pulmonary tumor emboli.
Why the study?
Pulmonary tumour emboli rarely present acutely without previous symptoms in patients with small cell lung carcinoma causing cardiovascular collapse.
Case Report (n=1)
Pulmonary tumour emboli from small cell lung carcinoma can rarely present as acute cardiovascular collapse without prior symptoms.
Acute unexplained collapse may signal occult SCLC with tumour emboli; case reports leave open true incidence and diagnostic pathways.
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 carcinoma of the bronchus. Patients suffering with pulmonary tumour emboli often 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.

Wong et al. (2000) conducted a case report in Small cell lung carcinoma with acute cardiovascular collapse (n=1). Small cell lung carcinoma with pulmonary tumour emboli was evaluated on Acute cardiovascular collapse. Small cell lung carcinoma can present as acute cardiovascular collapse due to pulmonary tumour emboli without any previous history of symptoms.
