摘要 目的探讨颅内原发性生殖细胞肿瘤(primary in-tracranial germ cell tumor,PIGCT)的病理类型和临床特征。方法对16例颅内PIGCT进行临床病理观察,其中12例进行免疫组化染色。结果生殖细胞瘤7例,肿瘤由大小一致的圆形或多边形细胞构成,呈巢团状分布,细胞界限清楚,胞质透亮,细胞核大、居中,核仁明显,间质可见淋巴细胞浸润;成熟性畸胎瘤4例,肿瘤内可见成熟的外、中、内胚层成分;卵黄囊瘤2例,由未分化间叶成分和原始腺上皮成分组成,分界不清,呈疏松网状结构,可见透明小体;混合性生殖细胞瘤2例,其中1例为生殖细胞瘤混合胚胎性癌,另1例为生殖细胞瘤混合未成熟畸胎瘤;绒毛膜上皮癌1例,由大而异型的细胞滋养叶细胞、中间滋养叶细胞及合体滋养叶细胞构成,伴大量出血。结论颅内PIGCT是一类罕见的肿瘤,准确的病理学诊断对临床治疗具有重要的指导意义。
