Malignant fibrous histiocytoma of the heart presenting as hemoptysis. Association with pseudothrombocytopenia.
A 24-year-old patient presented with hemoptysis. Pulmonary evaluation was unrevealing. After being lost to follow-up, he again presented with worsening symptoms and physical findings of severe pulmonary hypertension. A large left atrial mass was found on echocardiogram. This was subsequently found to be a malignant fibrous histiocytoma. He also had pseudothrombocytopenia due to platelet cold agglutinins. Left atrial masses must be considered in unexplained hemoptysis.
