We report the case of a 57-year-old patient with multiple myeloma, characterized by extramedullary involvement of the rectum at presentation. Malignant plasma cells were found to produce carcinoembryonic antigen (CEA), a tumor antigen more commonly associated with rectal adenocarcinomas.
我们报告了一例57岁的多发性骨髓瘤患者,其特征为就诊时直肠出现髓外浸润。发现恶性浆细胞产生癌胚抗原(CEA),这是一种更常见于直肠腺癌的肿瘤抗原。
