Acute presentation of choriocarcinoma: a case study and review of the literature

We report an unusual case of a 27-year-old male with an acute presentation of choriocarcinoma. The patient presented with unstable vital signs, severe anemia and a widened arterial pulse pressure following a several day history of testicular pain. He was subsequently diagnosed as having testicular choriocarcinoma with multiple hepatic metastases and large hemorrhagic para-aortic lymph nodes. The widened pulse pressure persisted during fluid resuscitation and correction of both the anemia and hypotension, and only narrowed after the initiation of chemotherapy. A literature review indicates that metastatic testicular choriocarcinoma is a rare but aggressive malignancy that often presents with acute symptoms and signs that cause patients to seek emergency care. We summarize the reported cases of "acute" testicular choriocarcinoma presentation and briefly discuss its relationship to widened arterial pulse pressure.
