摘要 目的探讨子宫恶性苗勒管混合瘤(malignant mixed Mullerian tumor,MMMT)的临床病理学特征、免疫表型、诊断及鉴别诊断。方法采用免疫组化EnVision法对4例MMMT进行检测并复习相关文献。结果肿瘤呈息肉状生长,由上皮和间质两种成分构成,2例上皮成分为子宫内膜样腺癌,1例为浆液性癌,1例为黏液腺癌,4例间质成分均为横纹肌肉瘤。免疫表型:上皮成分CKpan(4/4)、vimentin(2/4)和Pax-8(3/4)均阳性,间质成分CKpan(2/4)、vimentin(4/4)、desmin(4/4)、MyoD1(1/4)、CD10(1/4)、p16(3/4)和p53(3/4)均阳性,Pax-8、SMA、S-100和CD68均阴性。结论子宫MMMT是一种少见的高度恶性上皮和间质混合性肿瘤,具有独特的临床病理学特征,预后差。
