Here, we report an adult case of intra-abdominal testicular cancer after surgical treatment of an undescended testis in infancy. A 36-year-old male patient was accidentally diagnosed with a tumor in the pelvic cavity by ultrasonographic examination. He had hematuria and the human chorionic gonadotropin beta subunit level was slightly elevated. T2-weighedmagnetic resonance imaging revealed a well-defined and highly intense mass. Since these findings suggested intra-abdominal testicular cancer, laparoscopic surgery was performed to remove the mass. Laparoscopy revealed an intra-abdominal tumor accompanied by a looping vas deferens entering the left inguinal canal. The distal part of the looping vas had already been removed from the external inguinal ring. The pathological findings revealed a pT1 seminoma. The patient has been recurrence-free for 12 months. The present case implies the importance of careful investigation and treatment for intra-abdominal testicular cancer, since intra-abdominal testis might have been overlooked at the time of surgery for undescended testis.
在此，我们报告一例成年男性腹腔内睾丸癌病例，该患者婴儿期曾因隐睾接受过手术治疗。一名36岁男性患者经超声检查意外诊断出盆腔内有肿瘤。他有血尿，人绒毛膜促性腺激素β亚基水平略有升高。T2加权磁共振成像显示一个边界清晰、信号强度高的肿块。由于这些表现提示腹腔内睾丸癌，遂行腹腔镜手术切除肿块。腹腔镜检查发现腹腔内有一肿瘤，伴有一条迂曲的输精管进入左腹股沟管。迂曲输精管的远端已从腹股沟外环处切除。病理检查结果显示为pT1期精原细胞瘤。该患者已无复发存活12个月。本病例提示对于腹腔内睾丸癌进行仔细检查和治疗的重要性，因为在隐睾手术时腹腔内睾丸可能被忽视。
