Solitary extramedullary plasma cell tumors, although uncommon, have been reported with increasing frequency over the last few years. Approximately 5 to 10 percent of the tumors arise in the gastrointestinal tract. This report demonstrates that a solitary anaplastic cecal extramedullary plasmacytoma can mimic a polypoid carcinoma, both grossly and, to an extent, microscopically. Immunoperoxidase stains for cytoplasmic immunoglobulin proved useful in establishing the correct diagnosis.
孤立性髓外浆细胞瘤虽然不常见，但在过去几年中报道的频率有所增加。约5%至10%的肿瘤发生在胃肠道。本报告表明，孤立性间变性盲肠髓外浆细胞瘤在大体和一定程度的显微镜下表现上都可酷似息肉样癌。细胞质免疫球蛋白的免疫过氧化物酶染色在确立正确诊断方面很有用。
