Extramedullary plasmacytoma (EMP) of the gastrointestinal tract is an extreme rarity. Clinical manifestations of EMPs are varied, depending on the position and progress of tumor. Here we report a case of an EMP involving rectum in an 80-year-old, male patient with a change of bowel habit. Computed tomography scanning confirmed a circumscribed, iso-attenuating mass with the obvious heterogeneous enhancement. Patient received the surgical resection by laparoscope and the plasmacytoma was finally confirmed by the pathology. Furthermore, we made a literature review about the EMP of gastrointestinal tract to get the further study. Finally, we found out there is no specificity in imaging examination. Diagnosis of EMP still depends on the histopathology.
胃肠道髓外浆细胞瘤（EMP）极为罕见。EMP的临床表现多样，取决于肿瘤的位置和进展情况。在此，我们报告一例80岁男性直肠EMP患者，其有排便习惯改变。计算机断层扫描证实为边界清晰、等密度肿块，强化明显不均匀。患者接受了腹腔镜手术切除，病理最终确诊为浆细胞瘤。此外，我们对胃肠道EMP进行了文献复习以进一步研究。最后，我们发现影像学检查无特异性。EMP的诊断仍依赖于组织病理学。
