精巣セルトリ細胞腫の1例 : 本邦症例のアンケート調査を加えて

Abstract

We report a case of Sertoli cell tumor of the testis. A 33-year-old man visited our hospital with the complaints of macroscopic hematuria and fever. The left testis was swollen on palpation. Serum levels of human chorionic gonadotropin-β and lactate dehydrogenase were not elevated, while α fetoprotein was slightly over the normal range. Ultrasonography showed a hypoechoic lesion in the left testis. There was no evidence of retroperitoneal lymph node enlargement or distant metastasis on computed tomography. A left orchietectomy was performed under the diagnosis of left testicular tumor. The tumor, measuring 20 mm in size was histologically diagnosed as benign Sertoli cell tumor. No adjuvant therapy was performed. Neither recurrence nor evidence of metastasis has been detected for 6 months postoperatively.
