The fourth case of bilateral successive testicular tumors of different cell types is reported (seminoma and embryonal carcinoma), and the English literature on bilateral testicular tumors from 1965 to 1975 is reviewed. The absence of direct organ extension or demonstrable metastatic lymphatic or vascular involvement points to the primary origin of these lesions.
报告了第四例双侧连续发生的不同细胞类型睾丸肿瘤（精原细胞瘤和胚胎癌），并对1965年至1975年英文文献中关于双侧睾丸肿瘤的内容进行了综述。这些病变缺乏直接的器官扩展或可证实的转移性淋巴或血管受累，提示其为原发性起源。
