本文回顾复习100例睾丸生殖细胞肿瘤。分析各亚型的病理形态特征。卵黄囊瘤可有肝样、卵黄囊样、宫内膜样、乃至肠样分化;疏松的空状结构、透明小球(PAS染色阳性)有助于与胚胎性癌相鉴别。免疫过氧化物酶标记,keratin和CEA对诊断有一定意义。β—HCG是绒癌和胚胎性癌中合体滋养细胞的特异性标记。精原细胞瘤也可表达异位β—HCG。
This review reviews 100 cases of testicular germ cell tumors. Analysis of each subtype of pathological features. Yolk sac tumor may have liver-like, yolk sac-like, endometrial-like, and even intestinal-like differentiation; loose hollow structure, transparent pellets (PAS staining positive) contribute to the identification of embryonal carcinoma. Immunoperoxidase markers, keratin and CEA have some significance for the diagnosis. Beta-HCG is a specific marker for syncytiotrophoblasts in choriocarcinomas and embryonal carcinomas. Seminoma can also express ectopic β-HCG.
