精巣固定術後に発生した精巣腫瘍の1例

Abstract

A case of testicular tumor occurring after orchiopexy is presented. The patient, a 21-year-old male, who had undergone bilateral orchiopexy 14 years before was admitted to our clinic on February 17 in 1992 because of left testicular tumor. Computed tomography showed left inguinal and paraaortic lymphnode metastases. Left high orchiectomy was performed. The tumor was histologically diagnosed to be mixed tumors of embryonal carcinoma, yolk sac tumor and choriocarcinoma. After two courses of chemotherapy consisting of cisplatin, etoposide and bleomycin (PEB regimen), LDH and tumor markers (HCG, HCG-beta) returned to the normal range. The size of retroperitoneal metastasis was significantly reduced and inguinal metastasis disappeared. Therefore retroperitoneal and left inguinal lymphadenectomy were performed. Pathological examination of the resected retroperitoneal and left inguinal lymphnodes revealed embryonal carcinoma and no residual tumor cells, respectively. Additionally, two courses of chemotherapy were performed after surgery. His postoperative course was uneventful and ten months of follow-up showed no evidence of recurrence.
