Primary Myosarcoma of the Heart
Report of a Case Associated with Malignant Carcinoids and Pancreatic Heterotopia
Precordial pain and pericarditis were the early manifestations of this cardiac tumor. Discovery of bony metastases preceded detection of a rapidly growing intrathoracic mass, erroneously considered a bronchiogenic carcinoma invading the heart. Changing murmurs, chest pain, transient arrhythmia, intermittent fever, and progressive weight loss were the outstanding clinical features. Necroscopy revealed a primary cardiac tumor with metastases to pelvic bones, vertebrae, and lung, as well as malignant carcinoids and heterotopic pancreatic tissue.
