Primary cardiac neurilemoma.

A rare case of primary cardiac neurilemoma arising in the right atrium is reported. The patient was a 55-year-old woman who was treated for 20 years with drug and radiation therapy for a metastatic ovarian carcinoma. The cardiac tumor was an incidental finding at autopsy. Both light and electron microscopic examination of the tumor confirmed the Schwann cell origin of the neoplasm. Review of the literature reveals only one other unequivocal report of a primary cardiac neurilemoma.
