title: [Burned-out testicular tumor diagnosed triggered by paraneoplastic neurological syndrome: a case report].
abstract: We report a case of burned-out testicular tumor. A 41-year-old man was referred to our department with swelling of iliac lymph nodes detected by computed tomography screening for cerebellar atrophy. Lymph node biopsy revealed metastasis of seminoma. Ultrasound examination showed an irregular hypoechoic area in his left testis. We diagnosed paraneoplastic neurological syndrome secondary to burned-out testicular tumor. So, we underwent left orchiectomy and chemotherapy. He remains free from disease recurrence 15 months after treatment.
