This is an additional report of a case which Kinsui, et al. reported in 2000. A primary testicular tumor metastasized to the para-aortic lymph node in 6 years after the first high orichietectomy. In this case, we performed retroperitoneal lymph node dissection. After 4 months, the levels of 5-hydroxy indole acetic acid (5-HIAA), serotonin, urinary 5-HIAA were normalized without recurrence. This indicates testicular carcinoid needs long-term follow up.
