Germ cell tumors (GCTs) are relatively rare neoplasms considered to be curable malignancies since the introduction of cisplatin. The presence of neck metastasis has been reported, with fewer reports of metastatic mature teratoma. In this study, 3 cases of "benign neck" metastasis in patients with GCT between 1998 and 2010 were reviewed retrospectively. In all 3 cases the presenting clinical sign was a left lower neck mass, leading to the diagnosis of the primary site in the testis. All had surgical salvage following chemotherapy, with benign lesions or mature teratoma in histopathology of the neck mass. Chemotherapy was followed by salvage lower-half neck dissection showing benign features in the neck specimen, even though malignancy was proven histologically in other areas. Only 1 patient had a postoperative chyle leak, which resolved spontaneously after several days. Neck dissection is recommended in those patients because malignancy cannot be excluded.
