Chemotherapy-responsive primary cardiac lymphoma presenting as pericarditis and acute heart failure
摘要
Primary cardiac lymphomas (PCLs) are a rare subset of malignancies, representing a very small percentage of reported cancer patients. Even among primary cardiac tumors a diagnosis of lymphoma is rare, making a standard of care difficult to establish.
Case presentationHere we report the case of a patient who presented with chest pain and dyspnea who was initially diagnosed with pericarditis. Further imaging revealed a large obstructive right atrial mass with pathologic diagnosis of aggressive B-cell lymphoma. The patient was initiated on multiagent chemotherapy with daEPOCH-R comprising etoposide, prednisone, cyclophosphamide, vincristine, and rituximab with subsequent improvement in heart failure symptoms and tumor markers. Doxorubicin was added upon normalization of ejection fraction. The patient developed central nervous system relapse three months after completion of chemotherapy.
ConclusionsThis case describes the diagnostic evaluation and treatment of a patient with primary cardiac lymphoma. In contrast to other cardiac tumors, most patients with PCLs are treated with chemotherapy alone. Despite this, mortality remains high. When aggressive tumor biology is present, rapid initiation of high intensity chemotherapy is feasible. Our patient showed rapid clinical improvement and resolution of his cardiac mass in response to the daEPOCH-R regimen. This case illustrates the value of a multidisciplinary approach to establish a rare diagnosis and initiate prompt treatment for an unstable patient.
