高齢者に初発したセミノーマの1例

Abstract

Testicular tumor is seen exclusively in men from 30 to 50 years old. In elderly men, the incidence of testicular tumors is rarer than that of other malignant tumors. Herein we report a case of an elderly patient with a testicular tumor comprised solely of seminoma. A 60-year-old man was seen at the urologic clinic of Osaka Kita Municipal Citizen's Hospital because of painless swelling of the left scrotal contents. At the time of clinical visit, physical examinations and scrotal sonography showed a fist-sized mass with solid echo pattern in the left scrotum. He was hospitalized for the exploration of the suspected testicular tumor. The testicular mass was removed surgically through the left inguinal incision. Histopathological examinations of the resected tumor revealed pure seminoma. Chest film, computerized axial tomography, retroperitoneal ultrasound study and specific tumor markers were all negative which indicated stage 1 testicular tumor confined to the scrotal region according to Dixon and Moore's staging. He received adjuvant irradiation at the level of mediastinal lymph node after the operation. Postoperatively, he recovered well without any evidence of recurrence. In this report, the prognosis of non-bulky pure seminoma in elderly men are briefly reviewed in association with a conventional therapy to this disease in elderly patients described in the literature.
