Cutaneous T-cell lymphoma (CTCL) is a rare group of extra-nodal non-Hodgkin's lymphomas resulting in infiltration of the skin by the malignant cells. Sézary syndrome (SS) and mycosis fungoides (MF) are the most common subtypes, and infectious complications are the major cause of death in such patients. The presence of implantable cardiac devices (ICD) and CTCL make the patient more vulnerable to the device-related infective endocarditis (IE) caused by methicillin-resistant staphylococcus aureus (MRSA). The need for reimplantation of ICD should be assessed in detail and non-cardiac conditions should be considered while making such decisions. Herein, we report a unique case of non-ischemic cardiomyopathy with an implantable cardiac defibrillator (ICD), who later developed CTCL, complicated by the recurrent right-sided IE which is caused by MRSA.
