Abstract

The phenomenon of "burnout" in an extragonadaL germ cell tumor is characterizd by regression of testicular tumor. This condition is rare and particular. We report the case a 52-year-oLd male with left flank pain that radiated to external genitalia. Physical examintion showed a painLess and hard mass in the left flank; also a mass in left testicle. Abdominal computed tomography revealed an isodense and homogeneous mass located in retropentoneal area below the Left renal artery and above the common iliac artery. Histological analysis tumor retroperitoneaL reported a germinoma; while testicular atrophy and fibrosis was tified. These types of tumors are surgically treated with chemotherapy and I or and the prognosis is good.
