The authors report the case of a 66 year old man with a Boden stage I adenocarcinoma of the rete testis treated by orchiectomy and adjuvant chemotherapy. Lung metastases developed 46 months later and were responsible for death despite further chemotherapy. Adenocarcinoma of the rete testis is an exceptional tumour, as only 23 cases satisfying the criteria defined by Feek and Hunter have been reported in the literature. The prognosis is poor even in the apparently localized forms (5 year survival less than 25%) and local recurrences and lung and/or hepatic metastases are frequent. Radiotherapy and chemotherapy appear to have little value.
