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.

摘要

原发性心脏淋巴瘤是一种罕见的心脏肿瘤，通常起源于B细胞，累及心脏右侧。我们报告一例极其罕见的原发性心脏T细胞淋巴瘤，仅累及二尖瓣。一名58岁的女性，人类T细胞白血病病毒1阳性，因严重二尖瓣反流接受了二尖瓣置换术。二尖瓣的术后病理诊断为T细胞淋巴瘤。进一步评估显示，除二尖瓣外无其他恶性病变。据我们所知，这是首例局限于二尖瓣的原发性心脏T细胞淋巴瘤病例。
