title: Primary Cardiac T-Cell Lymphoma Localized in the Mitral Valve.
abstract: Primary cardiac lymphoma is a rare cardiac tumor, and usually originates from B cells and involves the right side of the heart. We present an extremely rare case of primary cardiac T-cell lymphoma involving the mitral valve alone. A 58-year-old woman who was positive for human T-cell leukemia virus 1 underwent mitral valve replacement because of severe mitral regurgitation. The postoperative pathologic diagnosis of the mitral valve was T-cell lymphoma. Further evaluation revealed no malignancy, except for the mitral valve. To the best of our knowledge, this is the first case of primary cardiac T-cell lymphoma localized in the mitral valve.
