Insights
Primary cardiac lymphoma, a rare form of Diffuse Large B-cell Lymphoma (DLBCL), can present with cardiac symptoms. Prompt diagnosis and R-EPOCH chemotherapy can lead to remission and improved outcomes.
Area of Science:
- Cardiology
- Oncology
- Hematology
Background:
- Diffuse Large B-cell Lymphoma (DLBCL) is the most common non-Hodgkin's lymphoma subtype.
- Primary cardiac involvement by DLBCL is exceptionally rare.
- Cardiac lymphoma often presents with subtle, atypical symptoms, complicating diagnosis.
Observation:
- A 60-year-old male presented with intermittent palpitations.
- Palpitations were diagnosed as ventricular tachycardia.
- Cardiac imaging revealed a right ventricular mass, confirmed as DLBCL via biopsy.
Findings:
- The patient received R-EPOCH chemotherapy (rituximab, etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin).
- Treatment led to symptomatic resolution of palpitations.
- A significant reduction in the cardiac mass size was observed.
Implications:
- Early detection of primary cardiac lymphoma is vital for improving patient survival.
- An interdisciplinary approach is essential for managing this rare cardiac malignancy.
- This case underscores the importance of considering lymphoma in cardiac masses with atypical presentations.
Abstract:
Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of non-Hodgkin's lymphoma. However, primary cardiac involvement is rare, often presenting with subtle and atypical symptoms that complicate diagnosis and management. We present the case of a 60-year-old man who presented with intermittent palpitations of unclear origin, later identified as ventricular tachycardia. Imaging showed a right ventricular cardiac mass, and biopsy confirmed a diagnosis of DLBCL. He was treated with the chemotherapy regimen rituximab, etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin (R-EPOCH), resulting in symptomatic resolution of palpitations and a reduction in the size of the cardiac mass. Early detection is crucial to improving survival in primary cardiac lymphomas and highlights the importance of an interdisciplinary approach in managing this rare cardiac malignancy.
