頻回に再発する陰嚢水腫を契機に発見された異時性両側精巣腫瘍の1例

Abstract

We report a case of metachronous bilateral testicular tumors combined with hydrocele. A 46-year-old male presented with frequently recurrent left hydrocele. His medical history included a stage IIA right testicular tumor, which had been treated with right high orchiectomy and retroperitoneal lymph node dissection 22 years ago. Magnetic resonance imaging (MRI) showed hydrocele and a low intensity area in the left testis, and the patient underwent left high orchiectomy. After cytological examination of the hydrocele it was categorized as class V, and after a pathological study it was diagnosed as seminoma and embryonal carcinoma. Since postoperative computed tomography showed lung metastasis, treatment with bleomycin, etoposide, and cisplatin (BEP) was indicated. Three courses of BEP produced a complete response. No recurrent testicular tumor was seen at 3 months after the BEP therapy. A metachronous testicular tumor should be considered in patients with a history of testicular tumors who frequently develop recurrent hydrocele.
