title: Archenteronoma (yolk sac tumors).
abstract: Ten cases of archenteronoma are reviewed with a follow-up between 2 mo and 7 yr. Their presentation was similar to that of rhabdomyosarcoma except for testicular tumors that may present as a hydrocele. A good prognosis was found with tumors amenable to primary resection and chemotherapy. Other tumors are best treated initially with chemotherapy before relatively conservative surgery, radiotherapy being used either pre- or postoperatively.
