Right Ventricular Epicardium-Originated Cardiac Lymphangioma: A Rare Tumor and Rare Origin.

Abstract

Tumors of the heart are uncommon, and lymphangioma is one of the rarest forms of this pathologic process. We describe an asymptomatic patient whose tumor was detected incidentally during coronary artery bypass operation. We detected a spongiform thin-layered mass covering about one-third of the right ventricular epicardium. Excisional biopsy was performed, and the main operation continued. Cardiac lymphangiomas are rare tumors of the heart and mostly benign. In general, surgical excision is performed when it is diagnosed. We detected the lesion incidentally; for this reason, we took only an excisional biopsy specimen. After exact pathologic diagnosis, the patient was observed with routine medical follow-up.
