A 36-year-old male was referred to our hospital with left scrotal swelling. Computed tomography revealed a massive tumor in his left scrotum. The tumor extended along the gonadal vein extraperitoneally forming a massive tumor. Pathological examination showed a mixed-type germ cell tumor. Despite several chemotherapeutic treatments, the tumor continued to grow, and the patient died 28 months later after his first presentation at our institution. Autopsy revealed that the tumor comprised rhabdomyosarcoma and mature teratoma. We could not find useful tumor markers to facilitate the diagnosis of rhabdomyosarcoma. However, we recommend rebiopsy or palliative operation as options for re-diagnosis in case of resistant germ cell tumor. Here, we present a case of testicular tumor that exhibited different pathological examination results before and after treatment.
