title: Diagnosis of anterior chamber metastasis by serologic marker found during anterior chamber paracentesis.
abstract: A 29-year-old man developed anterior uveitis unresponsive to intensive topical and systemic therapy. He had recently completed a course of chemotherapy with apparent response and resolution of metastasis from a mixed germ cell tumor (embryonal carcinoma and seminoma). Anterior chamber paracentesis was nondiagnostic on two occasions for metastatic cells. At the time of his second paracentesis a tumor marker, human chorionic gonadotropin-beta subunit, was used to confirm the diagnosis of anterior chamber metastasis to the eye.
