Secondary Cardiac T-Cell Lymphoma Presenting with Syncope and Refractory Complete Atrioventricular Block: A Case Report

Cutaneous t-cell lymphomas constitute a rare category of non-hodgkin lymphomas, which may involve the heart in the timeline of their natural course as an infrequent picture with a poor prognosis. syncope, either due to outflow obstruction or conduction block, is also an uncommon presentation of cardiac metastasis. we herein describe a 35-year-old man, who presented with weight loss, dyspnea of 6 months’ duration, an indolent skin ulcer in the left flank, lower limb deep vein thrombosis (dvt), and recurrent syncope. he underwent implantation of a permanent pacemaker due to a complete heart block and received anticoagulants for the dvt. skin biopsy demonstrated a t-cell lymphoma. the syncopal episodes ceased thereafter. echocardiography and computed tomography scan revealed cardiac metastasis, which responded to systemic chemotherapy. in the first follow-up visit after 3 months, he was still pace maker-dependent. however, the dvt was partially resolved, and the symptoms had disappeared.
