IntroductionPersistent lymphatic drainage following retroperitoneal lymph node dissection for testicular tumor is an uncommon complication.Case presentationWe describe a 21-year old man of Caucasian origin who had metastatic non-seminomatous germ cell tumor of the testis, and underwent retroperitoneal lymph node dissection, nephrectomy and partial inferior vena cava excision for a residual mass. The patient subsequently developed persistent lymphatic drainage causing foot drop that eventually responded to conservative medical and surgical measures.ConclusionThis postoperative condition usually responds well to conservative measures but has the potential for serious morbidity if it is not managed appropriately.
