[Testicular tumor following orchiopexy: a case report].

A 36-year-old male with history of left orchiopexy at age 11 received medical examination at the emergency department of our hospital with a left painful inguinal tumor as the chief complaint. A surgeon examined and suspected a femoral hernia. However, he noticed the patient having a tumor in the left scrotum as well, and referred the patient to our department. Alpha-fetoprotein was within the normal range, but beta-human chorionic gonadotropin and lactate dehydrogenase were slightly elevated. We diagnosed the case as a left testicular tumor and performed left high orchiectomy. On histopathological examination, the tumor was a seminoma and the left inguinal tumor was a lymph node metastasis (3 x 4 x 5 cm). After operation, the tumor markers became normal and radiographic examination showed no evidence of metastasis to the retroperitoneal lymph nodes and to other organs. Subsequently, the patient was given 2 courses of systemic chemotherapy (bleomycin, etoposide, cisplatin) as an adjuvant therapy. At present, eleven months after operation, he showed no evidence of recurrence. To the best of our knowledge, there are 47 reported cases of this disease including ours in Japan.
