Primary pulmonary leiomyosarcoma: case report and review of literature.

A case of primary leiomyosarcoma of the lung is added to the literature. Previously, 66 cases were documented. This is a case of a 55-year-old male, a pulmonary cripple for many years, with a collapsed left lower lobe found by roentgenogram, verified by bronchoscopy and bronchograms. Biopsy of lesion was reported as low grade leiomyosarcoma. Despite pulmonary function studies showing a vital capacity of 37% of predicted normal, a left pneumonectomy was preformed. Postoperatively, the patient had a tachycardia which gradually decreased in the next several months. Two months following operation pulmonary function studies were essentially unchanged from those made preoperatively. Arterial gas studies are presented pre and postoperatively.
