[Giant testicular tumor: a case report].

We report a case of giant testicular tumor. A 30-year-old man visited our department complaining of a painless swelling of the right scrotal contents. In chest X-ray and abdominal computerized tomography (CT) there were no abnormal findings. Serum alpha-fetoprotein, human chorionic gonadotropin and lactate dehydrogenase levels were normal. Right high orchiectomy was performed. The size of the removed specimen was 13.5 x 8.5 x 7.5 cm, and weight 530 g. The pathological diagnosis was immature teratoma. The patient has received no further therapy. There has been no recurrence for 7 months postoperatively.
