title: A case of leiomyosarcoma originating from pulmonary vein, occluding mitral inflow.
abstract: Cardiac leiomyosarcoma is a very rare entity that is found in less than 0.2% of all cardiac tumors. Because of its rarity and classification problem, there are few prospective studies about therapy and outcomes. Generally, diagnosis is delayed because of the nonspecific nature of the symptoms and by the time of diagnosis, most cases present with large tumors. Primary treatment of these tumors is still complete surgical resection. In this study we present a myxoid leiomyosarcoma originating from a pulmonary vein and extending into the left atrium, occluding mitral inflow in a woman 49 years of age. The tumor was totally removed. Open heart surgery is the acceptable approach for the management of intracardiac tumors, which may cause obstruction of blood flow through the heart.
