Late recurrent seminoma: 18 years after bilateral orchidectomy in patient with bilateral stage one testicular seminoma.

Late recurrence of stage I seminoma is an uncommon event. We reported a patient with seminoma recurred 18 years after the initial bilateral orchidectomy for bilateral stage I seminoma. He was on surveillance after the initial treatment and remained disease free for 18 years. He then presented with liver mass and diagnosed as recurrent seminoma. Systemic chemotherapy and subsequent hepatectomy for residual hepatic tumour mass were performed and the disease was cleared. The incidence and management of the late recurrence of seminoma would be discussed.
