[A case of solitary bone metastasis of testicular seminoma 6 years post orchiectomy].

A 40-year-old man visited our hospital in August, 2007 with the complaint of gait disturbance. Six years ago he had had right high orchiectomy for treatment of stage I seminoma at another hospital. The magnetic resonance imaging (MRI) examination showed a small tumor and compression fracture in the eighth thoracic vertebrae. Emergency spinal decompression with bone biopsy was done. The pathological diagnosis of the bone was metastasis of seminoma. He was treated with 3 courses of BEP (bleomycin, etoposide and cisplatin) therapy and external beam radiotherapy (36 Gy) was performed. His symptom of gait disturbance disappeared gradually, and was evaluated to be in complete remission. He has been alive with no evidence of recurrence for 3 years.
