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.
