case_images: Heavy intervillous acute and chronic inflammatory infiltrates could be observed (Figure 1), admixed with variable amounts of increased perivillous fibrinoid deposition, highlighted by special phosphotungstic acid haematoxylin (PTAH) stain (Figure 2). Extreme narrowing of already collapsing intervillous space by inflammatory infiltrates was seen (Figure 1).
