case_images: Ultrasonography revealed a mass with a heteroechoic pattern and 4-cm diameter (Fig. 1).
case_images: Computed tomography findings in the patient. A partially enhanced localized tumor was detected in his left testis, with no distant metastasis or lymph node swelling

case_images: Computed tomography revealed a partially enhanced localized tumor in his left testis, without any distant metastasis or lymph node swelling (Fig. 2).
case_images: Macroscopic appearance of the resected testis. The white arrow indicates the macroscopically recognized normal testicular tissue that was subsequently cryopreserved. The black arrow indicates the testicular tumor

case_images: Immediately after the removal of the testis, we sampled the normal testicular tissue that was macroscopically divided from cancer tissue (Fig. 3).
case_images: Histopathological findings of the resected testicular tumor. Hematoxylin-eosin stain of the embryonal carcinoma and yolk sac tumor (100x) (a) and immature teratoma (100x) (b)

case_images: The pathological diagnosis was a germ cell tumor comprising tumors of more than one histological type (pT1N0M0; embryonal carcinoma 50%, immature teratoma 30%, yolk sac tumor 10%, seminoma 5%, and choriocarcinoma 5%; Fig. 4).
case_images: Histopathological findings of resected normal testicular tissue. Numerous seminiferous tubules, including Sertoli cells, spermatogonia, spermatocytes, and several early round spermatids but no late spermatid were identified, indicating late maturation arrest (Johnsen score, 6) (400x)

case_images: Fig5
case_images: TESE contained numerous seminiferous tubules, including Sertoli cells, spermatogonia, spermatocytes, and several early round spermatids but no late spermatid. The histological diagnosis was late maturation arrest (Johnsen score, 6; Fig. 5).
