[Metastatic endometrial sarcoma of the right ventricular outflow tract associated with disseminated intravascular...

A case of myocardial metastasis of endometrial sarcoma to the right ventricular outflow tract is described. A 56-year-old woman was admitted with ecchymoses of lower limbs in September in 1995. Laboratory findings included thrombocytopenia and an increase of fibrinogen degradation products due to disseminated intravascular coagulopathy (DIC). Transesophageal echocardiography (TEE) demonstrated a large mass both in the right ventricular outflow tract and the proximal pulmonary artery. The mass was excised including base of the stalk. Cryoablation was employed on the endocardium where the stalk was originated. With pathological examination, the mass was identified to be endometrial sarcoma. The patient achieved an uneventful recovery and DIC was improved dramatically in a week after operation. Thirty-three months after the surgery, she has been well and free from local recurrent tumor.
