[Contralateral inguinal metastasis from testicular seminoma]

We report the case of a 42-year-old patient with contralateral inguinal seminoma metastasis. He had a history of prior bilateral open inguinal hernia repair and scrotal vasectomy. Staging CT revealed no further lymphoma or organ metastases. After discussion of adjuvant treatment options and contacting a referral centre for testicular cancer, adjuvant treatment was performed with 3 cycles of cisplatin, etoposide and ifosfamide. The development of the contralateral inguinal metastasis is most likely caused by the prior inguinal and scrotal surgery, whereas a primary atypical retrograde metastatic route can't be ruled out. Physical examination of the inguinal lymph nodes should be performed in all patients with testicular cancer and prior inguinal and scrotal surgery.
