The "burned-out" phenomenon in germ-cell neoplasias is defined by the presence of an extragonadal germ-cell tumour with no tumour at the testis level where a series of distinctive histological lesions can be detected indicative of the earlier presence of an already disappeared testicle tumoration. Extragonadal germ-cell tumours with "burned-out" phenomenon show better evolution than their primary counterparts and are treated similarly to primary tumours of the testis. Currently, in the presence of retroperitoneal tumoration, a scrotal ultrasound study with high frequency transducers can lead to a suspected picture of tumoral involution. This paper contributes one retroperitoneal seminoma with "burned-out" phenomenon in the homolateral testis in a 35-year old patient. Available clinical and radiological criteria were enough to reach a suspected diagnosis. Homolateral orchiectomy and biopsy of retroperitoneal tumoration were performed, rounding treatment up with polychemotherapy. Evolution was good with immediate complete response.
生殖细胞肿瘤中的“消退”现象定义为存在性腺外生殖细胞肿瘤，而睾丸水平无肿瘤，在此可检测到一系列独特的组织学病变，提示先前存在现已消失的睾丸肿瘤。伴有“消退”现象的性腺外生殖细胞肿瘤比其原发性对应肿瘤具有更好的病程，其治疗方式与睾丸原发性肿瘤相似。目前，在存在腹膜后肿瘤的情况下，使用高频探头进行阴囊超声检查可得出肿瘤消退的可疑图像。本文报道了一名35岁患者，其腹膜后精原细胞瘤伴有同侧睾丸“消退”现象。现有的临床和放射学标准足以做出可疑诊断。进行了同侧睾丸切除术和腹膜后肿瘤活检，并辅以多药化疗完成治疗。病情进展良好，立即获得完全缓解。
