title: Pulmonary leiomyosarcomas.
abstract: Four cases of pulmonary leiomyosarcoma are presented. The characteristic histological features are described with specific reference to the criteria of malignancy. It is suggested that diagnosis by bronchoscopy provides insufficient material for histological grading and open lung biopsy is the diagnostic tool of choice. The available methods of treatment are discussed.
