Anaplastic Large Cell Lymphoma Growing in the Pacemaker Pocket

Abstract

An 88-year-old patient underwent pacemaker generator replacement. Shortly after the replacement, the pacemaker pocket became swollen and, assuming a hematoma, underwent percutaneous drainage. However, the swelling was due to an aggressive lymphoma located in the pocket. This is the first described case of T-cell lymphoma in a pacemaker pocket.

Keywords: cancer; cardiac pacemaker; electrophysiology.
