Relapse of unusual localization of classic seminoma with post-chemotherapy transformation

Germ cell tumor is the most common cancer among males in the 20–39 year-old age range, representing 21% of invasive cancer diagnose. The vast majority of testicular tumors in this age range are germ cell tumors. There are two types of malignant tumors, the pure seminoma cell and non-seminomatous germinal cell tumors (NGCT). We present the case of a patient who underwent a testicular tumor surgery, classic seminoma stage I, receiving two cycles of adjuvant carboplatin chemotherapy. During the follow up, an elevation on the alpha-fetoprotein level was observed, thus the final diagnosis was adenopatic recurrence of the Yolk Sac tumor. ----------------------------------------------------------------- Cite this article as : Urena MD, Legeren M, Galvez F, Villaescusa A, Aparicio J, Jurado JM, Blancas I, Sanchez MJ, Romera AL, Martinez AP, Quinonez E, Dulcey I, Puche JL.
