Schwannoma of the heart.

We present a case of a 55-year-old woman who complained of chest pain at rest. A mass was detected adjacent to her left atrium. The mass was completely excised, and a pathologic examination revealed it to be a schwannoma. Schwannomas are tumors that originate in the nerve sheath and are rarely detected in the heart. Here, we describe a rare case of primary schwannoma of the left atrium.
