We present a case of detection of a right atrial mass during surveillance echocardiography, mimicking myxoma. Cardiac magnetic resonance and computed tomography revealed infiltration into the pericardium, suggesting malignancy. Abdominal computed tomography showed multiple liver masses that were histologically positive for metastatic amelanotic melanoma. Under immunotherapy adequate remission was achieved.

我们报告一例在超声心动图监测期间发现右心房肿块的病例，该肿块酷似黏液瘤。心脏磁共振成像和计算机断层扫描显示肿瘤浸润至心包，提示为恶性肿瘤。腹部计算机断层扫描显示肝脏有多个肿块，组织学检查证实为转移性无色素性黑色素瘤。在免疫治疗下，病情实现了充分缓解。
