During the last Annual Meeting of the PPS held in Madrid this year, one of the oral presentations was about heterotopic liver tissue in the placenta. The published literature is poor and it became clear during the discussion that several colleagues had seen similar cases but not published them. Not only liver tissue heterotopia is found in the placenta, but also cortical adrenal tissue, adipose tissue and even a case of neural tissue within chorionic villi. It would be important to collect as many cases as possible in order to assess the issue of heterotopic tissues in the placenta, its mechanisms and possible implications. Please let us know if you have cases of heterotopic tissues in the placenta and would like to contribute to this study.
