摘要 目的探讨组织细胞肉瘤(HS)的病理学特点、特异性标志物的意义及相关的鉴别诊断。方法采用EnVision免疫组织化学方法检测6例发生于不同部位的HS。结果6例HS中男性5例,年龄1~65岁,中位年龄18岁,女性1例,77岁。组织形态学:肿瘤细胞弥漫浸润,大小不一,部分区域细胞呈上皮样,胞质丰富嗜酸性,核圆形或不规则形,核仁大而嗜酸,核分裂象多见,个别区域可见双核、多核及瘤巨细胞,6例肿瘤细胞间质中均可见多少不等的炎性细胞。免疫表型:6例患者肿瘤细胞CD。溶菌酶(lysozyme)、LCA阳性,4例灶性细胞S-100阳性或弱阳性,2例个别细胞CD43阳性、1例个别细胞CD蜘。阳性,Ki-67阳性率30%~90%,而CD21、CD35、CD4、CD1a、MPO、CD30、CD3、CD20、ALK、HMB45均阴性。结论HS诊断相对比较困难,需结合肿瘤的镜下形态学改变及免疫表型。LCA、CD68、lysozyme是比较特异性的免疫表型,对HS的诊断及鉴别诊断有较大意义。
