Figure 1a. H&E stains of placentas with typical characteristics of hypertension, Botswana. A. Distal villous hyperplasia – small round and elongate villi with large syncytial trophoblastic knots and abundant intervillous space. B. Severe decidual vasculopathy with atherosis. C.Chronic abruption. Figure 1b. H&E stains of placentas with infection and other non-hypertensive findings: A,B, and C are examples of findings that support and infectious cause of death: A. Necrotizing Funisitis – umbilical vein with transmural inflammation and necrotic neutrophil debri as a halo in Wharton's jelly. B. Acute villitis/microscopic abcess. C. Acute chorioamnionitis with multiple bacterial cocci present. D and E are other non-infectious findings: D. Villous maturational arrest (a term placenta with immature villi and centralized vessels) E. Hydrops placentalis – this placenta weighed >900 grams and showed diffuse acute villous edema.
