Linfoma cardíaco primario en el paciente anciano / Primary cardiac lymphoma in the elderly patient

Resumen Se presenta un caso clínico de linfoma cardíaco primario en un paciente anciano, y se explica tanto la aproximación diagnóstica, como el tratamiento que llevó a su remisión completa.

Abstract A clinical case of primary cardiac lymphoma in an elderly patient is presented, and both the diagnostic approach and the treatment that led to its complete remission are explained.

Linfoma cardiaco primario / Primary cardiac lymphoma

Los tumores cardíacos primarios son raros. Tienen una incidencia que varía entre 1,38 y 30 por 100.000 personas al año, un aproximado de 75-80 por ciento son benignos. El linfoma cardíaco primario representa el 1,3 por ciento de los tumores cardíacos primarios y el 0,5 por ciento de los linfomas extranodales. Se define como un linfoma no Hodgkin (LNH) que afecta solo al corazón y/o el pericardio. Su complejo sintomático puede incluir disnea, dolor torácico, fatiga progresiva, sudoración nocturna, pérdida ponderal, arritmias, síndrome de vena cava superior y un aproximado del 20 por ciento de los pacientes pueden desarrollar insuficiencia cardíaca aguda como primera manifestación. Sin embargo, la mayoría de ellos cursan con sintomatología inespecífica y son detectados de manera incidental. El linfoma no Hodgkin difuso de células B grandes es la variante histológica más frecuente. Presentamos un caso que inició con síntomas de insuficiencia cardiaca derecha, evolucionó desfavorable hasta su fallecimiento y se realizó el diagnóstico en la autopsia(AU)

Primary cardiac tumors are rare. They have an incidence that varies between 1.38 and 30 per 100,000 people per year, 75-80 percent are benign, approximately. Primary cardiac lymphoma represents 1.3 percent of primary cardiac tumors and 0.5 percent of extranodal lymphomas. It is defined as a non-Hodgkin's lymphoma (NHL) affecting only the heart and/or the pericardium. Its symptoms may include dyspnea, chest pain, progressive fatigue, night sweats, weight loss, arrhythmias, and superior vena cava syndrome. Approximately 20 percent of patients may develop acute heart failure as the first manifestation. However, most of them have nonspecific symptoms and are detected incidentally. Diffuse large B-cell non-Hodgkin's lymphoma is the most frequent histological variant. We report a case that began with symptoms of right heart failure, progressed unfavorably until death, and the diagnosis was made at autopsy(AU)

A Successful Case of Cardiac Operation and Chemotherapy for Primary Cardiac Malignant Lymphoma with Superior Vena Cava Syndrome / 日本心臓血管外科学会雑誌

Primary cardiac lymphomas are rare cardiac neoplasms with poor prognoses. We report a 61-year-old man who presented with superior vena cava (SVC) syndrome. Trans-thoracic echocardiography showed a 77×91-mm mass occupying the right atrium. The tumor obstructed the SVC. The deteriorating hemodynamics of our patient prompted a surgical intervention. We resected as much of the tumor as possible under cardiopulmonary bypass. The postoperative course was uneventful, and the SVC syndrome disappeared. Pathological examination was consistent with malignant lymphoma, diffuse large B-cell type. After cardiac operation, the patient was treated with rituximab, cyclophosphamaide, adriamycin, vincristin, and prednisone (CHOP-R). The patient has been in good health for 30 months without signs of recurrence.

A Case Report of Primary Cardiac Lymphoma: Diagnosis by Transvenous Biopsy

Primary cardiac lymphomas diagnosed antemortem are extremely rare. We present a case of primary cardiac lymphma diagnosed antemortem by transvenous biopsy under transesophageal echocardiographic guidance. The patient who was a 62 years old male presented with facial edema, dyspnea on exertion and syncope. The chest X-ray film showed double contour at right cardiac border and the ECG showed marked sinus bradycardia. Transesophageal echocardiography (TEE), chest computed tomography (CT) and magnetic resonance imaging (MRI) showed intracardiac tumor of right atrium, invasing interatrial septum and inlets of superior and inferior vena cava and lateral wall of right atrium. Abdominopelvic CT and bone scan failed to show any extracardiac location. Transvenous biopsy confirmed the diagnosis of malignant lymphoma (diffuse large cell, B cell type). After chemotherapy was begun, the tumor makedly shrunk and symptoms resolved. Primary cardiac lymphoma is extremely rare and almost uniformly fatal, but this case showed that early diagnosis and intensive che-motherapy might contribute to a better prognosis for patients with malignant lymphoma of the heart.
