BACKGROUND Although diffuse large B-cell lymphoma (DLBCL) is the most common subtype of non-Hodgkin lymphoma in adults, isolated cardiac recurrence of DLBCL which can cause fatal heart failure via various mechanisms is extremely rare. Furthermore, the frequency of recurrence of DLBCL more than 5 years after attaining complete remission is as low as 3.6%. The rate of complete remission and partial remission of DLBCL that have recurred 5 or more years after attaining the initial remission are reported to be 61% and 29%, respectively. CASE REPORT A 79-year-old female with a history of DLBCL at the age of 63 years was transferred to our hospital because of cardiogenic shock. Although cardiac tamponade was suspected, her hemodynamics did not improve with pericardiocentesis. Thoracotomy showed an elastic to hard tumor occupying most of the right ventricular wall. Cytological examination of the pericardial effusion and histological examination of a biopsy of the tumor yielded a diagnosis of DLBCL; this information was available only post mortem. Immunostaining of a biopsy specimen suggested that her cardiac tumor was a recurrence of her lymphoma diagnosed 16 years previously. Bone marrow aspiration was not performed; no recurrences were detected in any other site. This patient thus appeared to have an isolated cardiac recurrence of DLBCL. CONCLUSIONS When managing a patient with a cardiac tumor and a past history of DLBCL, albeit more than a decade previously, establishing a histological diagnosis as early as possible would facilitate possible successful treatment and a good prognosis.

A 46-year-old woman with quiescent lupus presented with worsening pleuritic chest pain and dyspnoea. Bedside echocardiogram confirmed large pericardial effusion with cardiac tamponade. Emergency bedside pericardiocentesis was performed. Pericardial fluid cytology confirmed diffuse large B cell lymphoma, stage four on positron emission tomography. Conventional rituximab, cyclophosphamide, doxorubicin, vincristine and prednisolone chemotherapy achieved good response in all sites except the pericardium. Progressive cardiac involvement was complicated by atrioventricular conduction block requiring permanent pacemaker. Second-line palliative chemotherapy was performed.

Primary effusion lymphoma (PEL) is a rare type of non-Hodgkin lymphoma, usually presenting as serous effusions without detectable tumor masses, and it is universally associated with the human herpesvirus 8 (HHV8). In contrast, cases of HHV8-negative effusion lymphoma have been reported and termed as HHV8-negative PEL-like lymphoma. Here, we have reported a rare case of HHV8-negative PEL-like lymphoma that developed in the left atrium tumor 4 years after the pericardial drainage. A 74-year-old female was admitted due to cardiac tamponade caused by massive pericardial effusion. Pericardial drainage was performed, and cytopathologic examination of the fluid revealed atypical lymphoid cells consistent with an effusion lymphoma of B-cell lineage. The pericardial effusion was completely drained, and complete remission was achieved. After 4 years of the drainage, she developed syncope caused by arrhythmia. A computed tomography scan revealed a large tumor in the left atrium and multiple swollen mediastinal lymph nodes. Biopsy of one of the lymph nodes was performed, and its histology was consistent with diffuse large B-cell lymphoma. She was treated with chemotherapy, including rituximab, and complete remission was achieved again. Thus, our experience suggests that careful follow-up may be required in patients with HHV8-negative PEL-like lymphoma after complete remission has been achieved by the drainage.

Cardiac involvement during lymphoma often causes complications, including arrhythmia. A 68-year-old male with cardiac tamponade was diagnosed with diffuse large B-cell lymphoma with cardiac involvement based on the presence of the tumor mass in the myocardium and lymphoma cells in the pericardial effusion. He developed atrial fibrillation, ventricular tachycardia, and atrial flutter after initiating chemotherapy. Following chemotherapy, sinus rhythm was restored without invasive treatment for arrhythmia, while the cardiac mass disappeared. No recurrent arrhythmias were observed. In lymphoma with cardiac involvement, unexpected arrhythmias can emerge after initiation of chemotherapy, which could potentially be related to accelerated cardiac remodeling owing to the rapid relief of cardiac damage. Follow-up using electrocardiogram is thus necessary during chemotherapy for cardiac lymphoma, despite the absence of arrhythmia at the time of diagnosis.
