Incidental Finding of a Left Atrial Myxoma while Characterising an Autoimmune Disease

Although cardiac tumours are uncommon, cardiac myxomas account for more than fifty percent of all cases and are the most frequent primary cardiac tumour. They have a broad clinical spectrum, usually related to cardiac symptoms, peripheral embolic events or systemic manifestations. We present a case report of a 68-year-old man who presented with systemic symptoms and analytical features suggestive of an autoimmune disease. In the ensuing diagnostic procedures, a cardiac myxoma was found, and after surgical resection, both the systemic manifestations and the analytical abnormalities disappeared.
