that metastasis often occurs early in tumor progression. In early stage breast cancer, for example, a significant percentage of patients exhibit circulating tumor cells (CTC's) and disseminated bone marrow tumor cells (DTC's) [1,2]. More direct experimental evidence for " early metastasis " has been observed in studies of transgenic mice expressing a cancer-causing oncogene where the primary ca...

Acute mesenteric ischemia (AMI) is a rare vascular emergency associated with a high mortality rate. The most common cause of AMI is cardiac emboli from thrombi associated with atrial fibrillation or following myocardial infarction. We present a case of AMI caused by a unique source of emboli, confirmed as an embolization of a cardiac sarcoma to the small bowel by matching biopsies obtained from...

Calcific emboli from a calcific aortic stenosis is an uncommon event, usually following local trauma, as from cardiac surgery or left heart catheterization or as a sequel to bacterial endocarditis. We report what we believe to be the first case of a spontaneous calcareous emboli demonstrated by cranial computed tomography. In this patient, systemic hypertension and mild aortic insufficiency may...

Pulmonary hypertension in association with carcinomatosis was first described over 100 years ago (Bristow, 1868). Kane et al. (1975), however, found only 23 reported cases of multiple tumour emboli causing dyspnoea, adding 16 of their own. Only four of these cases were reported from the British Isles. Sarcomas, although commonly metastasising to the lungs have not previously been reported as gi...

A patient underwent exercise testing during evaluation for unexplained dyspnea. Evidence of ventilation-perfusion mismatch was noted and subsequent testing revealed multiple pulmonary emboli. Ventilation perfusion parameters by serial exercise testing progressively improved during the course of the patient's illness but did not totally normalize. A discussion of the utility of exercise testing ...

The hearts of 14 patients dying early after replacement of a calcified aortic or mitral valve were examined for the presence of calcific coronary emboli. The incidence of embolization as shown by x-ray film was 92-9 per cent. The number of emboli in individual cases ranged from 4 to 119. Replacement of an aortic valve was associated with a more severe embolization than replacement of a mitral v...
