A 20-year-old man was admitted to our hospital with persistent cough and dyspnea. He had bilateral distention of the jugular veins, and swollen lymph nodes were palpable in the right subclavicular region. Plain X-ray and computed tomography (CT) of the chest showed a solid soft tissue mass in the upper mediastinum, with leftward displacement of the trachea and complete obstruction of the superior vena cava. Mediastinal radiotherapy (1.8 Gy/day) and methylprednisolone (100 mg/day) were started immediately. Biopsy of the right subclavicular lymph nodes revealed metastatic seminoma. The patient was referred for chemotherapy, which was performed with a combination of cisplatin, bleomycin and etoposide (BEP). A partial response was observed after completion of 3 cycles of chemotherapy, but there was no further tumor shrinkage after additional salvage chemotherapy. The patient is being followed up on an outpatient basis and has been free of recurrence for 32 months after intensive treatment.

Recurrence of seminoma in the scrotum after inguinal orchidectomy is extremely rare. Herein, we report the second case in the literature of recurrence of seminoma in the scrotum following inguinal orchidectomy for stage I seminoma.

We report an extremely rare case with bilateral and symmetric dumbbell ganglioneuromas of the cervical spine in an elderly patient. A 72-year-old man came by ambulance to our hospital due to progressive incomplete paraplegia. Magnetic resonance imaging demonstrated bilateral symmetric dumbbell tumors at the C1/2 level. We performed total resection of the intracanalar tumor, aiming at complete decompression of the spinal cord, and partial and subtotal resection of foraminal outside portions. Histopathological examination of the surgical specimen indicated the tumor cells to be spindle cells with the presence of ganglion cells and no cellular pleomorphism, suggesting a diagnosis of ganglioneuroma. Although the surgery was not curative, the postoperative course was uneventful and provided a satisfactory outcome. This is the fourth known case of cervical ganglioneuromas of the bilateral symmetric dumbbell type.
