[Systemic embolism in a renal transplant patient. Echocardiographic demonstration of bronchial carcinoma with intracardiac invasion].
A 45 year old female renal transplant patient was admitted for subacute ischaemia of a lower limb. Echocardiography was performed and showed the presence of bronchial carcinoma with intracardiac invasion. The tumour was confirmed by thoracic computerised tomography and by bronchoscopy. Histological investigation of bronchial biopsies and of the arterial embolism extracted at surgery showed large cell malignant disease. The tumour partially responded to chemotherapy and the patient survived for 5 months. Extension of a bronchial carcinoma to the left atrium is a classical complication in autopsy reports but rarely a source of systemic embolism. Echocardiographic diagnosis of this condition is very rare. The incidence of malignant diseases is higher in renal transplant patients than in the general population but this has not been verified for bronchial carcinoma. Echocardiography played an essential role in this case, detecting the tumour and its extension, indicating a poor prognosis and guiding treatment.
