title: Acquired pulmonary stenosis due to pleomorphic adenocarcinoma.
abstract: Acquired pulmonary stenosis was diagnosed in a 53 year old woman presenting with the unusual feature of an oral murmur. Mediastinotomy showed extensive malignant tissue surrounding the pulmonary artery, although a mediastinal mass was not evident on chest radiographs. Histological examination confirmed a pleomorphic adenocarcinoma, which has not previously been reported as causing acquired pulmonary stenosis.
