Novo caso de placentite chagásica no Triângulo Mineiro, observou-se, à mioroscopia óptica, o parasitismo de miócitos das paredes vasculares, fato não descrito anteriormente na literatura. O estudo à microscopia eletrônica revelou. (1) abundantes amastigotas do Trypanosoma cruzi em células de Hofbauer; (2) proliferação fibroblástica e colágena na parede de pequenas artérias e arteríolas, ocluindo-lhes, por vezes, o lume; (3) parasitas em células musculares degeneradas e fibroblastos da parede vascular. Este é o primeiro relato de placentite chagásica humana com análise ultra-estrutural. In a new case of chagasic placentitis in the Triângulo Mineiro, we have observed, through optical microscopy, the parasitism of miocytes of the vascular walls, a fact that was no previously described in literature. The electron microscopic study revealed: HI plentiful amastigotes of Trypanosoma cruzl in Hofbauer cells; (2) fibroblastic and collagen proliferation on the walls of small arteries and arterioles, occluding, at times, the lumen; (3) parasites in degenerated muscular cells and fibroblasts of the vascular walls. This is the first report of human chagasic placentitis with ultrastructural analysis.
