Not a Coincidental Concurrence of Breast Carcinoma and Cardiac Myxoma: Case Report

Background: Myxoma has been considered to undergo a simple and benign process but not always so. Case presentation: A female patient was admitted for evaluation of left breast nodule. Physical examination showed facial pigmentation, left breast nodule and 3/6 diastolic murmur at the mitral valve area. Preoperative echocardiography revealed a massive mobile left atrial mass attaching to the interatrial septum causing obstruction to mitral orifice. Histopathologic investigation confirmed the left atrial mass to be myxoma and left breast nodule to be cancer. Carney complex was considered and lifelong follow-up was advised. Conclusion: Cardiac myxoma may present as a part of a systematic disease entity. In patients with a combination of breast nodule and facial pigmentation, transthoracic echocardiography examination is advised to guide decision-making.
