Intraplacental choriocarcinoma: a case report

Abstract

A recent paper has again drawn attention to the occurrence of intraplacental choriocarcinoma. We present a similar case in which a small intraplacental choriocarcinoma was identified after delivery of a full-term stillborn fetus. Interpretation of this lesion was influenced by the presence of normal villi and its full significance appreciated only after diagnosis of choriocarcinoma in the mother. This case presents histological proof that choriocarcinoma may arise from an otherwise normal placenta.
