title: [The necessity of mediastinal lymph node dissection for yolk sac tumor of the anterior mediastinum].
abstract: Combined treatment with preoperative chemotherapy and surgical resection is the universally accepted effective treatment of mediastinal yolk sac tumors. However, a problem on the need and efficacy of lymph node dissection in mediastinal yolk sac tumors has been not enough discussed in the past. We reported a case of mediastinal yolk sac tumor with nodal metastasis. As described in this paper, the resection of the primary lesion including the regional lymph nodes en bloc should be recommended for mediastinal yolk sac tumors.
