[A case report of testicular tumor in a dialysis patient].

A hemodialysis patient suffering from testicular tumor is reported. The patient was a 43-year-old man who had been receiving hemodialysis for 1 year. The patient consulted our hospital complaining of left testicular swelling and mild pain. Because of hen-egg-size enlargement and irregular surface of the left testis, high orchiectomy was performed under the diagnosis of testicular neoplasm. The diagnosis made after the microscopic examination was seminoma with a portion suspected as choriocarcinoma. No metastasis was revealed by computer tomography and chest X-ray photography. Considering that the patient was on dialysis and clinical diagnosis was stage 1, we did not perform radiation therapy nor lymph node dissection and the patient has been under careful observation.
