Cardiac lipoma in a patient with a history of malignant tumours: a case report.

Cardiac tumours are relatively rare. Most of them do not cause clinical symptoms so that prior to the introduction of modern methods of investigation they were predominately incidental findings during autopsies or open heart surgery.We present the case of a 63-year-old German man with a past history of malignant melanoma and renal cell carcinoma who presented with a right atrial lipoma and a suspicious lesion in the right lower lobe of the lung. Surgical excision of the cardiac lipoma was performed and a biopsy of the lung mass was done which diagnosed a moderately differentiated adenocarcinoma.
