title: Neck mass as the first presentation of testicular choriocarcinoma.
abstract: Choriocarcinoma is a highly malignant tumor of the testis and usually occurs as a component of mixed germ cell tumor. The testicular enlargement may be subtle, and the patient may present with metastasis, the neck being one of its least reported locations. A case of testicular choriocarcinoma in a 24-year-old man who presented for the first time with metastatic neck mass is reported here. This presentation, although very rare, can be a great diagnostic and therapeutic challenge and should be considered in the differential diagnosis of cervical masses occurring in young males.
