A 78-year-old man presented with a 1-month history of exertional dyspnoea, anorexia, weight loss and night sweats. On physical examination the patient had a cachectic appearance and multiple 2‑ to 4‑cm-diameter skin lesions (Fig. 1a). Electrocardiography (Fig. 1b) showed ST-segment elevation in leads V1 and V2 and ST-segment depression from V3 to V6 with no dynamic changes in serial electrocardiograms. Transthoracic echocardiography revealed large heterogeneous masses adhered to the myocardium with no clear cleavage plane, an intermediate echogenicity and involving the right ventricle, the atrioventricular groove and the large vessels (Fig. 1c; Electronic Supplementary Material, videos 1–3). He was admitted and a skin biopsy was performed which was compatible with diffuse large B‑cell lymphoma.
Cardiac lymphoma usually occurs in the context of metastatic involvement and can manifest in a variety of ways, depending on the location of the masses [1, 2]. This patient had no acute myocardial infarction criteria . We hypothesise that the ST changes were explained by the infiltration or displacement of the myocardium by the tumour, mimicking underlying myocardial infarction.
