Anterior segment metastases from an ovarian choriocarcinoma.

A 28-year old woman with ovarian choriocarcinoma developed a uveitis in her left eye. Subsequently, a mass was observed in the anterior segment of that eye together with a subconjunctival mass that appeared to extend from it. Biopsy of the subconjunctival nodule showed two different cell types consistent with the cytotrophoblastic and syncytiotrophoblastic elements typical and choriocarcinoma. No abnormalities of the posterior segment were found on careful examination. Treatment consisted of systemic chemotherapy with a variety of therapeutic agents, argon laser photocoagulation of tumor seedings in the anterior chamber angle, radiation to the eye, and finally, subconjunctival injections of methotrexate. The eye became blind and painful and was enucleated. Histopathologic examination revealed residual tumor cells in the anterior segment indicating treatment changes, but there were no abnormalities posteriorly. Choriocarcinoma metastatic to the eye has been reported infrequently, and this is the first case in which anterior segment metastases have been observed and the effects of treatment thoroughly documented.
