Coronary pseudoaneurysm: an unreported complication of Castleman's disease.

Castleman's disease is considered a benign disease with very few reports of local invasion into adjacent structures. We present the first reported case of myocardial involvement with Castleman's disease. Careful preoperative planning allowed the placement of a left ventricular assist device with eventual heart transplantation after complete resection of the tumor and unsuccessful myocardial revascularization.
