Salvage lymph node dissection is a therapeutic option in patients with nodal-only recurrence after radical prostatectomy. Although this operation does not achieve a complete cure in the majority of cases, it can prolong survival and help postpone hormonal therapy in selected patients while being a relatively safe procedure. The authors describe a case study of a radical prostatectomy patient with radiologically proven recurrence of prostate cancer limited to an internal iliac node. He underwent salvage lymph node dissection with a complete biochemical response. Remission lasts 13 months following surgery and the patient is currently without the need for androgen deprivation therapy.Key words: salvage lymph node dissection prostate cancer radical prostatectomy neoplasm recurrence.
