title: Primary mediastinal leiomyosarcoma.
abstract: Primary leiomyosarcoma of the mediastinum is a very rare malignant mesenchymal tumor, which may arise in the soft tissue of the mediastinum or from the great vessels. Due to its rarity and nonspecific clinical symptoms, the correct diagnosis and proper management are often delayed and not well established. We report a 55-year-old woman with a large right-sided mediastinal leiomyosarcoma with adhesion to the pericardium and right middle lobe, which was completely removed via right thoracotomy along with pericardial resection and right middle lobectomy.
