RESUMEN
Fibroelastoma is a rare cardiac tumor. Even more rare is multilocalization of these tumors as well as their residence inside the cardiac chambers. Here, the case is reported of a 46-year-old male with three fibroelastomas of which only two were diagnosed preoperatively. The third tumor was discovered during surgery on the endocardium of the left ventricular wall, 2 cm away from the base of the anterolateral papillary muscle after a thorough examination of the ventricle had been instituted. Emphasis must be placed on the importance of performing such an examination during the excision of fibroelastomas, as a failure to address multiple lesions - although their existence is rare - might expose the patient to dangers of future embolization or reoperation.
