Cardiac relapse of extranodal NK/T-cell lymphoma manifesting as incessant ventricular tachycardia: a case report.

ABSTRACT:

Background

Cardiac tumours are rare but affected patients may present with symptoms mimicking other cardiac diseases. The most frequent symptoms include heart failure, arrhythmias, or embolic phenomena.

Case summary

A 39-year-old man with a history of extranodal NK/T-cell lymphoma of the nasal type (ENKTL-NT) in clinical remission presented at our department with incessant ventricular tachycardia. The arrhythmia could only be controlled with a combination of intravenously administered beta-blockers, ajmaline, and amiodarone. Diagnostic workup excluded ischaemia, but imaging revealed a tumour located in the apex of the left ventricle. Endomyocardial biopsy confirmed the diagnosis of cardiac relapse of ENKTL-NT. Upon chemotherapy no further arrhythmias developed.
