Extratesticular germ cell neoplasms without apparent testicular primary tumors are rare. The origin of these neoplasms has been debated in the literature for decades. With the advent of effective chemotherapy for extratesticular germ cell neoplasms, the origin of these tumors becomes more than academic. We report on 3 cases of retroperitoneal germ cell neoplasms with microscopic intratesticular primary tumors. All patients with extragonadal germinal cell tumors of the testes should undergo thorough investigation for an occult testicular primary tumor despite a normal testis examination. We review previously reported cases of extratesticular germ cell neoplasms without an apparent testicular primary tumor.
无明显睾丸原发性肿瘤的睾丸外生殖细胞肿瘤很罕见。几十年来，这些肿瘤的起源在文献中一直存在争议。随着针对睾丸外生殖细胞肿瘤的有效化疗的出现，这些肿瘤的起源变得不仅仅是学术问题。我们报告3例伴有微小睾丸内原发性肿瘤的腹膜后生殖细胞肿瘤。所有睾丸性腺外生殖细胞肿瘤患者，尽管睾丸检查正常，也应接受对隐匿性睾丸原发性肿瘤的全面检查。我们回顾了先前报道的无明显睾丸原发性肿瘤的睾丸外生殖细胞肿瘤病例。
