title: Chorangiocarcinoma: an unusual tumour of the placenta. The missing link?
abstract: A tumour occurring in an otherwise normal placenta presented the vascularity of a mature chorangioma but was surrounded by a neoplastic trophoblastic proliferation. A chorangioma with an atypical associated trophoblastic proliferation has never been reported in any of nearly 500 cases of chorangiomas described in the literature. The possibility of a combined lesion (for which we propose the term chorangiocarcinoma) is emphasized. It cannot be excluded however that chorangiomas could be, in rare cases, true neoplasms rather than hamartomas.
