Computed tomography showed a normal testis in the right hemiscrotum and a 58\u2009mm heterogeneous mass in the right inguinal area. No testis was observed in the left hemiscrotum. The vascular structures extended from the right inguinal mass to the left renal vein. Consequently, the left testicular tumor was diagnosed as transverse testicular ectopia, and a left orchiectomy was performed. The histological diagnosis was seminoma stage pT2. Furthermore, left para\u2010aortic lymph node metastasis developed 10\u2009months postoperatively.
