Three cases of bilateral germ cell tumor of testis were presented. Of these three, one showed similar histological features of seminoma in both tumors and two had different histological features of embryonal Ca.+teratoma, and embryonal Ca.+seminoma in the respective cases. We reviewed 78 cases of such tumors in the Japanese literature. Of these, 54 showed similar histological features, while twenty four did not. The review showed that the incidence of seminoma was highest in bilateral tumors. Bilateral tumors with different histology had a longer interval than those with similar histology. Seminoma occurred only in adults.
本文报告三例双侧睾丸生殖细胞瘤。其中一例双侧肿瘤均表现为精原细胞瘤相似的组织学特征，另两例分别表现为胚胎癌+畸胎瘤和胚胎癌+精原细胞瘤不同的组织学特征。我们回顾了日本文献中78例此类肿瘤。其中，54例表现出相似的组织学特征，24例则不然。回顾显示，双侧肿瘤中精原细胞瘤的发生率最高。组织学不同的双侧肿瘤比组织学相似的双侧肿瘤间隔时间更长。精原细胞瘤仅发生于成年人。
