目的 提高成人睾丸畸胎瘤的诊治水平。方法 回顾了16例成人睾丸畸胎瘤患者的临床、病理及治疗资料。结果9例患者为成熟畸胎瘤,7例患者为未成熟畸胎瘤。11例就诊时为Ⅰ期肿瘤的患者中,有2例术后发生转移,5例患者就诊时已发生转移,转移率为43％。转移均发生在腹膜后淋巴结,转移灶病理:6例为畸胎瘤,1例为畸胎瘤合并卵黄囊瘤。结论 成人睾丸畸胎瘤可发生转移,转移灶中可有其他非精原细胞瘤成分,Ⅰ期肿瘤转移率较低,但其治疗原则应与非精原细胞瘤一致。
Objective To improve the diagnosis and treatment of adult testicular teratoma. Methods The clinical, pathological and therapeutic data of 16 adult patients with testicular teratoma were reviewed. Results 9 cases were mature teratomas and 7 cases were immature teratomas. Of the 11 patients who presented with stage I tumors at the time of presentation, 2 had postoperative metastases and 5 patients had metastases at the time of presentation. The metastatic rate was 43%. Metastasis occurred in retroperitoneal lymph nodes and metastasis pathology: teratoma in 6 cases and yolk sac tumor in 1 case. Conclusion Adult testicular teratoma can metastasize, and there may be other non-seminoma components in metastasis. The metastasis rate of stage I tumors is low, but the principle of treatment should be consistent with non-seminoma.
