Choriocarcinoma metastatic to maxillary gingiva.

A rare metastatic lesion is presented in a 77-year-old black man. The primary disease was fulminating from the time of admission, and diagnosis was established by oral biopsies. The unusual features in this case, in addition to the rarity of the tumor, are the age and race of the patient, the peculiar metastases, and difficulty in identifying a primary site.
