[A Case of Giant Testicular Tumor with Pelvic and Inguinal Lymph Nodes Metastasis].

A 51-year-old man visited our hospital since he had noticed remarkable increase in size of left scrotal contents. Computed tomography revealed left testicular swelling, retroperitoneal, pelvic and left inguinal lymph nodes. Serum testicular tumor markers (α fetoprotein, β-human chorionic gonadotropin, lactate dehydrogenase) were elevated. Low left orchiectomy was performed due to swelling of the left inguinal lymph node. The excised specimen weighed 3,400g. Pathological findings were non-seminoma. Although there was no operation history of scrotal groin, there was metastasis in the left inguinal lymph node ; therefore, the stage of disease was T2N3M1a. According to the postoperative values of tumor markers, his condition was judged as "good prognosis" in the International Germ Cell Consensus Classification (IGCCC), and he underwent 3 courses of bleomycin, etoposide and cis-platin (BEP) therapy. Although the tumor markers decreased to the normal limit and the size of lymph node was remarkably decreased after 2 courses of BEP therapy, one course of EP therapy was added for further reduction of tumor size. For the residual lymph node metastasis, retroperitoneal lymph node dissection (RPLND) was performed. Then pelvic and left inguinal lymph node dissection was performed at a later date. Pathological findings of excised lymph nodes were only necrotic tissue. He is alive without disease recurrence three years after treatment.
