Cardiac myxoma with glandular elements: An unusual histologic variant with a brief review of the literature

Abstract

Cardiac myxoma with glandular elements is an unusual histologic variant of cardiac myxoma and constitutes 2%–5% of all cardiac myxomas. Here, we report a case of cardiac myxoma with glandular elements in a 34-year-old male, who presented with right-sided hemiparesis following a cardiovascular attack 2 months back. Echocardiography revealed a large right atrial mass measuring 3.5 cm × 3.5 cm × 2 cm. Under cardiopulmonary bypass, left atrial mass was excised. Histopathological and immunohistochemical examination of the mass confirmed the diagnosis of cardiac myxoma with glandular elements. It is important to recognize this variant to avoid misdiagnosis of metastatic adenocarcinoma due to its rarity as well as due to its unusual morphological features.
