(A) Color Doppler ultrasonography showed an enlarged, heterogeneous, macronodular right testicle with cystic areas. Both arterial and venous flow were preserved, but hyperemia of the abnormal testis was present. (B) The testis and spermatic cord were accessed via an inguinal incision.

Color Doppler ultrasound (Figure 1A) revealed an enlarged, heterogeneous, macronodular right testicle with cystic areas. The patient underwent a right radical orchiectomy via the inguinal approach (Figure 1B).
(A) The majority of the tumor comprises immature teratoma with a predominance of primitive neuroepithelium (bottom right) and a smaller primitive mesenchymal component (nodule of immature cartilage on the left). (B) There were rare small foci of yolk sac tumor with primitive glandular structures as well as a hepatoid focus demonstrating cords of immature cells with more abundant eosinophilic cytoplasm and occasional small nucleoli. (C) This focus is strongly AFP-positive.
