Primary mediastinal choriocarcinoma in an 18-year-old male with pulmonary and brain metastasis: A case report.

Abstract

Primary mediastinal choriocarcinoma, also known as non-pregnant choriocarcinoma, is a rare malignancy unrelated to pregnancy, with a higher incidence in males. And primary mediastinal choriocarcinoma is mostly associated with organ and lymph node metastasis, with rapid progression and poor prognosis. Here, we report an extremely rare case of the primary anterior mediastinal choriocarcinoma that occurred in an 18-year-old man with multiple metastases of the lung and brain.
