We present a case report of a relapse to the mediastinal lymph node alone, 38 months after orchiectomy on surveillance for stage I typical seminoma. The patient, a 63-year-old man, was treated with high inguinal orchiectomy for left testicular tumor and close follow-up. After 38 months from the initial treatment, the chest X-ray film and CT scan revealed mediastinal tumor. Fine needle aspiration cytology performed under the bronchoscopy showed seminoma cells. Complete remission was achieved after three courses chemotherapy of cisplatin, vincristine, methotrexate, peplomycin and etoposide (COMPE). He has continued to be clinically disease-free 8 months after completion of the treatment. According to the available data in the literature, 94% of the recurrences was detected within 3 years after orchiectomy, and 92% involved retroperitoneal lymph node metastases. This is a rare case who had a late relapse in the mediastinum alone.
