Leiomyosarcoma of the pulmonary trunk associated with pericardial effusion.

, 490-494. The case history of a patient with a leiomyosarcoma of the pulmonary trunk is presented. The clinical picture was dominated by unexplained shortness of breath, episodes of cough and haemoptysis, general weakness, and weight loss. Signs of a pericardial effusion and pulmonary stenosis developed a few weeks before death. Thoracotomy revealed an inoperable tumour arising from the pulmonary trunk and a large pericardial effusion. Microscopy of the tumour removed at necropsy showed a leiomyosarcoma.
