A case of primary carcinoid tumor of the right testis with metastases to the cervical and thoracic vertebrae and epidural is reported. A 53-year-old man was first recognized as being with dysthesia of the left arm and shoulder in April 1986. In June, 1987, he was admitted to the Neurology service, complaining of sudden occurrence of abasia. Myelography and computerized tomography demonstrated an epidural mass and several high density areas in the vertebral bodies of Th1 and Th2. The patient underwent laminectomy from C7 to Th2. At operation, the neurosurgeons noticed a tumor mass in the right scrotum and requested our consultation. Thus right high orchiectomy was performed. Pathological examination including Grimerius' and Fontana-Masson's stain revealed carcinoid tumor of the right testis associated with metastases to the spinal column. Postoperatively, tumor maker studies revealed elevation of blood 5-hydroxytryptophan and marked increase of urinary 5-hydroxy-indoleacetic acid excretion. They showed remarkable decreases after a course of PVB chemotherapy. The patient has been under our observation as an out-patient for the past 27 months with metastases. This is the first case of primary carcinoid tumor of the testis with metastases so far reported in the domestic literature.

The widespread introduction of LED lighting is expected to reduce greenhouse gas emissions because white LEDs will be the most efficient light sources in the near future. This paper describes trends in emission of greenhouse gases in Japan and compares the CO 2 emission of LED lighting with conventional lighting.[3] Japan Electric Lamp Manufacturers Association,
