Resumo: ABSTRACT The aim of this report is to describe a case of marked osseous metaplasia in the placenta associated with abortion in a mare. A 19-year-old Campolina mare with a history of multiple parturitions and absence of reproductive failure, aborted a fetus with approximately six months of gestation. There were no gross changes in the fetus and the placenta. Microscopically, there was multifocal replacement of fetal connective mesenchyme of the chorionic villi with well differentiated and partially mineralized osseous tissue (confirmed by von Kossa staining). To further characterize the collagenous component of the lesion, sections of the placenta were stained with Masson’s trichrome and Picrosirius red. Osseous tissue deposition had abundance of type I collagen. To the best of our knowledge, this is the first report of osseous metaplasia in the placenta of a mare associated with abortion at mid gestation, presumably due to placentary insufficiency.
