A 75 year old man with an eight month history of dysphagia and weight loss underwent pericardiocentesis for a massive pericardial effusion. The echocardiogram showed a mass in the left atrium, and computed tomography also showed distal oesophageal narrowing, which was found to be due to a malignant melanoma. The left atrial mass, investigated by immunoscintigraphy with technetium-99m labelled monoclonal antibody, was diagnosed as metastatic melanoma. This represents a rare case of primary oesophageal melanoma with left atrial metastasis.
一名75岁男性，有8个月吞咽困难和体重减轻病史，因大量心包积液接受了心包穿刺术。超声心动图显示左心房有一个肿块，计算机断层扫描也显示食管远端狭窄，发现是由恶性黑色素瘤引起的。通过用99m锝标记的单克隆抗体进行免疫闪烁扫描研究的左心房肿块被诊断为转移性黑色素瘤。这是一例罕见的原发性食管黑色素瘤伴左心房转移的病例。
